We started getting this error when we refactored the pause reducer to use isPaused

Good fix for new frontend. Won't work with old frontend, but not a regression and non blocking.

(Since you mentioned it :)) 

It does not work with the old frontend. I think you tested with the old frontend in Firefox, but not the old frontend in the Browser Toolbox. To enable it you need to :
- open BT
- select other panel than debugger
- close BT
- open BT 
- go preferences
- disable new frontend
- switch to debugger

It was already not working previously. We could check if isPaused is available and is a function. Not mandatory IMO.

Minor cosmetic feature, but allows to get rid of a JS error.

[Needs manual test from QE? If yes, steps to reproduce]: yes.
- use MacOS
