First time run immediately crashes

[johnmcdowall]

Just installed the gem, and I do have some events to show:

But the dashboard shows up with some placeholder skeletons, then immediately crashes:

I can circumvent the crash by adding return 0 if value.current.nil? || value.compared_to.nil? before the diff calculation. Happy to open a PR unless you want the comparable itself to have safer logic.

Seems fixed now.

Sadly I have this error now too.

I've created a fork to include the latest version and the fix for the shims described here: #40

I have more than 1000 events in my database that should be eligible.
