Incompitabilities with some apps - looping lockscreen, freezes, etc.

[Maxr1998]

Description There are multiple issues with the current lockscreen lifecycle which could trigger for some more or less special, but often widely used apps - regardless if using the Xposed app locker or the unreleased "no Xposed" option.

This can involve looping lockscreen :curly_loop:, crashing/freezing of the locked app :skull:, the locked app being minimized after the first launch/unlock :see_no_evil:, the lockscreen appearing when navigating in-app :flushed:, the lockscreen not appearing at all :running_man:

Affected apps (some of them, from issues and own tests)

• AOSP Browser :skull:
• Google Photos :see_no_evil:
• Hangouts :see_no_evil: :curly_loop:
• WhatsApp :flushed:, also call screen locked even though it shouldn't
• Google Keep :skull:
• Xposed Installer :curly_loop:
• ProtonMail :skull: (fix: unlock splash activity by default)
• Kik :running_man:
• Viber :curly_loop:
• Wire :see_no_evil:
