[telepathy-glib/master] Look for qualified properties in immutable a{sv}

[Will Thompson]

TpChannel was looking up "InitiatorHandle" where it should have been
looking up "org.freedesktop.Telepathy.Channel.InitiatorHandle". This
failed, and meant that TpChannel always called GetAll() on channels,
even if you used tp_channel_new_from_properties() in an attempt to avoid
this happening.
