[telepathy-gabble/master] Revert "Include xmlns on contents"

[Will Thompson]

This reverts commit dfce1b44821700212f35951931dd5e6bc1942946, which was
completely wrong: <content> stanzas are in the same namespace as their
parent <jingle> node, not in the namespace of their <description>.

I made this change because the codepath for producing <content>s for the
purpose of transport-info actions (which was separate) did so, so that I
could delete the redundant path.
