Ignore exception encountered when trying to clean up jobs during exit

The suggested workaround for this issue from the comments on
ludovicchabant#178 is to add any
offending file types to the gutentags exclude list. I don't want to do that,
since the file types causing me issues are ones with which I DO want to use
gutentags!
