Unscoping `default_scope` in associations has already supported (#17360
for preloading, c9cf8b8 for eager loading).
Fixes #20679.
Closes #16531.

ActiveRecord query cache is available when a connection is connected.
Therefore, query cache is unavailable when entering the ActiveRecord::Base.cache block without being connected.
```ruby
ActiveRecord::Base.cache do
Task.find(1) # access to database.
Task.find(1) # access to database. unavailable query cache
end
```
If we use query cache with batch script etc, we need to connect before that.
```ruby
Task.connection
ActiveRecord::Base.cache do
Task.find(1) # access to database.
Task.find(1) # available query cache
end
```
Before version 3.1, query cache had been enabled if a configuration was set up.
In order to solve the `DATABASE_URL` issue(#8074), ActiveRecord has checked whether a connection is connected or not.
Today, ActiveRecord.configurations respect `DATABASE_URL`.

Rails 5.1.2.rc1 regression - Clear offset cache on CollectionProxy reset/reload

The `@offsets` cache is used by FinderMethods to cache records found by
find_nth. This cache is cleared in AR::Relation#reset, but not in
CollectionProxy#reset or CollectionProxy#reload.
Because of this, since #29098, calling #first/#find_nth/etc after
calling #reload or #reset on an association could return a stale record.
This is an issue both when the full association target is loaded and
when the item is loaded in #find_nth.
This commit solves the problem by clearing the `@offsets` cache in
CollectionProxy#reset and CollectionProxy#reload.

Doing `Author.joins(:posts).merge(Post.joins(:comments))` does this
`SELECT ... INNER JOIN posts ON... LEFT OUTER JOIN comments ON...`
instead of doing
`SELECT ... INNER JOIN posts ON... INNER JOIN comments ON...`.
This behavior is unexpected and makes little sense as, basically, doing
`Post.joins(:comments)` means I want posts that have comments. Turning
it to a LEFT JOIN means I want posts and join the comments data, if
any.
We can see this problem directly in the existing tests.
The test_relation_merging_with_merged_joins_as_symbols only does joins
from posts to comments to ratings while the ratings fixture isn't
loaded, but the count is non-zero.

Don't map id to primary key in raw_write_attribute

The `raw_write_attribute` method is used to update a record's attributes
to reflect the new state of the database in `update_columns`. The hash
provided to `update_columns` is turned into an UPDATE query directly,
which means passing an `id` key results in an update to the `id` column,
even if the model uses a different attribute as its primary key. When
updating the record, we don't want to apply the `id` column change to
the primary key attribute, since that's not what happened in the query.
Without the code to handle this case, `write_attribute_with_type_cast`
no longer contains any logic shared between `raw_write_attribute` and
`write_attribute`, so we can inline the code into those two methods.

Avoid overwriting the methods of `AttributeMethods::PrimaryKey`
