Add tests for extensions getting installed

Fix #4080
Fix #4081

Test Plan:
- Completely retest each extension from scratch.
- Try cleaning your userProfileDir/Extensions but not the
  session-store-1 file, things should be recoverable / normal
- Try cleaning your session-store-1, things should be recoverable.
- Try manually setting your session-store-1 for 1passwrod from
  4.5.9.90 to 4.4.9.90 (replace all), edit `~/Library/Application\ Support/brave-development/Extensions/aomjjhallfgjeglblehebfpbcfeobpgk/4.5.9.90/manifest.json`
  and set the version inside the manifest to 4.4.9.90.  Move the
  folder to a subfolder called 4.4.9.90 as well.
- Start up and wait 10 minutes, it should update. Or you can run
  `require('electron').remote.session.defaultSession.updateClient.checkNow('aomjjhallfgjeglblehebfpbcfeobpgk')`
  to force the update.  about:extensions should show the new
  version.
