Fix HTML entities being parsed in GFM

Also fixes the spec so that it actually tests the thing it says it's

Closes #1308

Be more resilient in the case of missing omniauth settings

gitlab.yml. People who aren't using it shouldn't even have to put a
'false' entry in their config for it (and probably wouldn't, after an
upgrade).
