Fix QVersitReader::testReading unit test

The reader spawns a worker thread to perform reading and parsing,
which then emits state change signals back to the main thread.

Previously, signals emitted in one test case could interfere with
another test, as the event queue was not drained prior to performing
condition verification.

This commit applies more strict verification to the first test
and then ensures that the signals have been received before beginning
the second test.
