[totem-pl-parser] Specify G_PRIORITY_DEFAULT for signal emission idle sources

[Jonathan Matthew <jmatthew src gnome org>]

commit 6792ae8958edd1b60ce5278e0a125974309ab904

    Specify G_PRIORITY_DEFAULT for signal emission idle sources
    
    This avoids the situation where the async ready callback is called first
    because it has higher priority.
