gapplication: Fix a small leak on an error handling path

This was highlighted (but not introduced) by
0144feb41fc1819cec6415483bd8a61e64373aca. Previously the test coverage
didn’t cover this branch, I think.

`iter` was leaked, and at this point `parameter` had never been set, so
clearing it was unnecessary.
