Make generate_exchange_uuid() always return the passed ast_str pointer.

Browse Source 
I changed this code earlier to return NULL if it wasn't able to generate a UUID,
whereas the earlier code would always return the ast_str that was passed in.
Switch back to returning the ast_str, only set it to the empty string instead if
UUID generation fails.  We still do a validity check later which will catch this
and blow up if necessary.
