    gmain: Fix possible locking issue in source unref
    
    When unref'ing child sources, the lock is already held. But instead of
    passing TRUE to g_source_unref_internal it currently passes whether the
    lock was already held outside of the current invocation. Just pass TRUE
    to fix this possible issue.
