Resolve (partially) the issue with mentions without server.

Browse source 
Mastodon (mainly from the API) usually include mentions without server,
which is just stupid. This patch tries to resolve these broken mentions in
process_tags() by looking for a user name starting with it in the already
pre-populated tag list. As of now, this only works if the message is an
inReplyTo and the broken mention is the one of the original
(attributedTo) poster.
