PL/pgSQL: Extend test case

This test was supposed to check the interaction of INOUT and default
parameters in a procedure call, but it only checked the case where the
parameter was not supplied.  Now it also checks the case where the
parameter was supplied.  It was already working correctly, so no code
changes required.
