Avoid critical error in thread check if source is destroyed

The source can be destroyed by the time we complete the result, and
then the g_source_get_context(current_source) call will cause
a critical error. We check for the source being destroyed and avoid
the check in that case.

This means we miss the right-thread check in this case, but thats
merely a helper, so this is not critical.
