[Bug] Turning on and off automatic updates makes Paddy stop working
### Bug report
#### Expected behavior:
When turning on and off the automatic updates, I'd expect the plugin to work when turning it back on.


#### Actual behavior:
At some point (after turning on and off a view times), the plugin isn't working even though automatic updates are on. I need to quit Sketch to make it work again.


#### Steps to reproduce:
Turn automatic updates on and off a bunch of times (let some time pass in between, not sure exactly when this breaks).
