`zend_test_create_throwing_resource` sets the exception in the `test`
call frame and unwinds to `main`. It then throws for the `resource`
variable and verifies that the exception opline is set. However, it
wasn't set in `main`, it was set at the `test` call frame and rethrown later.
The assertion is too conservative, but the end result is right, so drop
the assertion.
Closes GH-17533.
