last_push_event widget considers fork events on the main project

Push events on the fork of the current project are considered to be shown besides the push events on the current project. Before we just consider fork events if exists a fork so we miss current project events if the current user has a fork.

Use gitlab-workhorse 0.7.11

Versions 0.7.9 and 0.7.10 crash on previously valid 'authBackend'
settings.

I don't know how many people are affected by this, 'normal' Omnibus
installations are not. (If they were gitlab.com would have stopped
working :) ). Still this is something we should not ship.
Unfortunately 8-11-stable uses 0.7.10 (but 8.11.0 does not). So I
think we need to put this in the next 8.11 patch release.
