Added a test.

Testing in the other direction (adding HANDLER and leaving VALIDATOR
unspecified, then dropping the validator) is slightly more complex
because I don't want to drop the built-in postgresql_fdw_validator. But
the patch in the other thread can be extended with a new test or two
also, which will cover that case.

Will backport all the way.
