RQ v0.11 changed worker_ttl

[tabletcorry]

The new version of RQ (v0.11) changed the way the default worker_ttl is accepted:

rq/rq@3133d94#diff-1aac421e8c53e895ee40f3b7dc63144fR158

So using Flask-RQ2's CLI breaks. The following works around this issue (by explicitly setting the default), until it is updated:

flask rq worker --worker-ttl 420

This fix would be to not pass the None to RQ, or to teach Flask-RQ2 the default in RQ.
