    testsuite, c++, coroutines: Correct a test intent.
    
    The intention of the series of tests numberef pr95615-* is to
    verify that entities created by the ramp and potentially needing
    destruction are correctly handled when exceptions are thrown.
    Because of a typo, one case was not being checked correctly (the
    return object).  This patch amends the check to test that the
    returned object is properly deleted.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/coroutines/torture/pr95615.inc: Check tha the
            task object produced by get_return_object is correctly
            deleted on exception.
