Fix database configuration when adding another config level
This is kind of hard to explain but if you have a database config with
another level like this:
```
development:
primary:
database: "my db"
variables:
statement_timeout: 1000
```
the database configurations code would chooke on the `variables` level
because it didn't know what to do with it.
We'd see the following error:
```
lib/active_record/database_configurations.rb:72:in
`block in find_db_config': undefined method `env_name' for [nil]:Array
(NoMethodError)
```
The problem here is that Rails does correctly identify this as not a
real configuration but returns `[nil]` along with the others. We need to
make sure to flatten the array and remove all the `nil`'s before
returning the `configurations` objects.
Fixes #35646
