Make DispatchQueue drain the queue immediatly from maybeEnqueueConsumer if run on the main thread
Currently things launched with `launchWhenCreated` will run after
`onStart` since `Dispatchers.Main` is used. With this change
maybeEnqueueConsumer will drain the queue synchronously if run on the
main thread which prevents this behavior.
Test: ./gradlew lifecycle:lifecycle-ktx:test
