Fix tests for change in PostgreSQL 14 behavior change. (#14310)

PostgreSQL 14 changed the behavior of `websearch_to_tsquery` to
improve some behaviour.

The tests were hitting those edge-cases about handling of hanging double
quotes. This fixes the tests to take into account the PostgreSQL version.
