test_predtest() neglected to consider the possibility that SPI_plan_get_cached_plan would return NULL. This led to a core dump if the input (incorrectly) contains more than one SQL command.

Back-patch to all supported branches, not because this is very significant (it's merely test scaffolding) but to make our world a bit safer for fuzz testing.
