We always enable Fission if the fission.autostart pref is true, even in Safe Mode. If a user is running into Fission stability problems, they won't be able to start Firefox to disable the fission.autostart pref if we enable Fission in Safe Mode.

We should probably fix this bug for Fission M6a because early dogfood testers are the users most likely to hit Fission stability issues.

This makes it easier to consider special conditions when checking the pref. It
currently returns false if safe mode is enabled.
