Fix some minor error-checking oversights in ParseFuncOrColumn().

Recent additions to ParseFuncOrColumn to make it reject non-procedure
functions in CALL were neither adequate nor documented.  Reorganize
the code to ensure uniform results for all the cases that should be
rejected.  Also, use ERRCODE_WRONG_OBJECT_TYPE for this case as well
as the converse case of a procedure in a non-CALL context.  The
original coding used ERRCODE_UNDEFINED_FUNCTION which seems wrong,
and is certainly inconsistent with the adjacent wrong-kind-of-routine
errors.

This reorganization also causes the checks for aggregate decoration with
a non-aggregate function to be made in the FUNCDETAIL_COERCION case;
that they were not is a long-standing oversight.
