Guard::Brakeman failed to achieve its <run_all>

Started getting this error since upgrading to guard 1.8.3, gist with backtrace here:

I'm not sure what changed in guard that's causing @tracker to be null during run_all, but adding @tracker ||= ::Brakeman::Scanner.new(@scanner_opts).process above line 58 seems to have fixed it for me, but probably isn't the right thing to do :P

I think the only downside to that is that it would have to reprocess the entire app each time run_all is run. Not ideal for an app that takes 6 minutes to process. I have no idea why that instance var would disappear. I'll see what's different in guard. Did you do a 1.8.2 -> 1.8.3 upgrade or are there more version to check?

Sidenote: I have no idea why return run_all unless @tracker.checks is in run_on_changes
