ApplicationList: Reset app menu screen when loading watch face

[vkareh]

This prevents the application list from loading in the last used screen and instead goes back to the first screen whenever the watch face is loaded.

Fixes #2006

Have you checked why the page number of the launcher is actually stored? I wouldn't want to apply a change that conflicts with the original intend of the code.

I think it would also be a good idea to check that the behavior reported in #2006 does not happen for other apps as well, like settings for example (that you can open with a double press on the button iirc)? Maybe the fix should be more generic than it currently is?

Yes. It was added as part of #217 with the description:

• Go back to the same menu page when we leave an app

This behaviour is preserved, as we only reset the page when we're not in an app.

This issue doesn't happen in the settings, since we don't store the current screen there.

Git bisect says the bug was introduced in 39bc166. There was no call to SetAppMenu removed in that commit... Why didn't the bug occur before?

The call to Settings::SetAppMenu() was done in the ctor of the Clock class, which was removed in this 39bc166 commit!

And I think the @vkareh found a better place for this in DisplayApp so that watch faces do not have to manage this state.
