Eliminate virtualbox galaxy template issues hack

``` irc
14:44 < jmchilton> problem: first time I start this virtualbox VM - Galaxy works. Second time mako hates me
(https://gist.github.com/anonymous/4d5b7b861a2c540275e8). Has anyone seen that - any ideas what
is causing it?

14:45 < erasche> insert a find database/cache/ -exec rm '{}' \; in run.sh? :P
14:46 < erasche> no haven't seen that though
14:46 < erasche> can you get at the mako template, is it missing the mako magic?
14:49 < jmchilton> well - wiping the cache does fix it thanks. I wish I understood the problem - but we have passed
the point where that is a reasonable hope I guess :)
14:50 < erasche> i'm guessing somewhere mako flubbed the generation of the templates and they were corrupted
14:50 < erasche> buuut no idea
14:54 < jmchilton> tool shed template cache doesn't need to deleted - odd. Alright hacking that it.
