Synned tags sometimes fail to get the media/fandom of the canonical tag

Description

Originally reported on Google Code with ID 3776
otwarchive v0.9.9.8

What steps will reproduce the problem?
1. Syn a new, unwrangled tag to an existing canonical tag
2. The synned tag should automatically add the media/fandom(s) of the canonical tag
(fandom tags add the media(s); character, relationship, and freeform tags add the fandom(s)).

This action is queued so slightly delayed (usually only 5-15 seconds, sometimes up
to a minute; when the tag is reloaded the fandoms/media will appear.)

However, sometimes this process seems to be dropped from the queue entirely, and the
media/fandom is never added. (This causes trouble because the tag will then just sit
in the unwrangled bins rather than moving to the appropriate media/fandom bin as expected;
and wranglers are used to synning and closing a tag without waiting around to double-check
that it's had the media/fandoms attached.)

There doesn't seem to be any consistency in which tags fail to get the media/fandom,
or when it happens. This has been an occasional problem since the fandom-adding was
queued; but since the Rails upgrade it's been happening much more frequently (when
I last wrangled it was about every 1 in 10 tags?)

Not sure if this is replicable in Test - I just tried with a dozen tags on Test and
they all worked fine; that may be just luck or else it's an issue specific to the Beta
servers?
