fix: Fix QUOTED_IDENTIFIERS_IGNORE_CASE parameter test (#2841)

Setting `QUOTED_IDENTIFIERS_IGNORE_CASE` in
`TestAcc_Parameters_QuotedIdentifiersIgnoreCaseCanBeSet` was interfering
with the tests being run on other branches. It resulted in seemingly
random `Database 'XYZ' does not exist or not authorized` errors for
database that exists, works moments before and moments after. Sequence
of example statements:

```

What was done:
- test `TestAcc_Parameters_QuotedIdentifiersIgnoreCaseCanBeSet` creates
new user and sets the `QUOTED_IDENTIFIERS_IGNORE_CASE` parameter on it
- fail-fast guards added to integration and acceptance tests setups to
prevent running tests when `QUOTED_IDENTIFIERS_IGNORE_CASE` is set to
true initially
