Hyper: updateChannel config param should be hot reloaded

[chabou]

When user change updateChannel setting to 'canary', for example, it should change Hyper behaviour instantly and should not require a restart.
Feed URL should be changed on the fly, and a new update check should occur directly after this config reload.

@chabou The idea is pretty good, but vscode when updated asks to restart 🤔

[chabou]

This not what I meant.
User should obviously restart after an update.
What I meant is to not have to restart Hyper after a config change.

@chabou I understand :D

I don't want to read, for Now desktop

Once the preference is checked, it will be applied immediately - no restart required.

and for Hyper

After that, restart the application

Been looking into this for the last couple days. The code isn't a big change but it seems like testing the autoUpdater is more difficult than I originally expected. Code signing on Mac is all new to me! Is there a way to test that this is working without getting a Developer ID Application so code signing works properly? It's quite expensive to enroll in the program through Apple.
