Fix `validates_uniqueness_off :field, :allow_nil => false`
Closes (#5853)
Uniqueness validator was not properly checking if there are any existing
records, when value was `nil` and column was text type. `nil` was
converted to string, which resulted in queries looking like:
```sql
SELECT 1 FROM "posts" WHERE "posts"."title" = '' LIMIT 1
```
instead of
```sql
SELECT 1 FROM "posts" WHERE "posts"."title" IS NULL LIMIT 1
```
