To solve this a little nicer, I decided to expand on the idea I introduced a while back with PullRequest::isSame, and add the corresponding method to HostedRepository. This made implementing the ::concurrentWith methods cleaner IMO.

These gauges report the number of active and pending WorkItems we have respectively in the BotRunner, summarized per WorkItem type using labels. To achieve this as nicely as I could, I refactored the BotRunner a little bit, moving all adds and removes for the active and pending maps to specific methods.
