tests: remove irrelevant assertions from test-aio

In these tests, the purpose of the initial calls to aio_poll and
g_main_context_iteration is simply to put the AioContext in a
known state; the return value of the function does not really
matter.  The next patch will change those return values; change
the assertions to a while loop which expresses the intention
better.
