Barnabás Pőcze 529b6fd1b8 test: loop: add test which destroys managed source before reentering 
Add a test which triggers two event sources in the loop's "before"
control hook, and destroys the second source in the loop's "after"
control hook, and then reenters the loop in the event handler of
the first source. At the moment, this test triggers a use-after-free.
