Disable retries for remote mirror update worker

By default, Sidekiq will retry 25 times with an exponential backoff.
This may result in jobs retrying for up to 21 days. That could lead
to an ever-increasing queue size for the remote mirror updates. The
mirrors will attempt to update again within an interval, which should
be sufficient.

See merge request !848

Added a weight filter reset scenario

Looks like we missed a scenario for testing weight filtering for EE.

I'm not 100% this is the correct implementation, maybe I have to `create(:weight)` but I did this in the web UI so will adjust the spec if they fail.
