Ask for the home role after the launcher has finished resuming; keep failed background checks quiet

First run (PRD SI-1)
- The request to become the default home app never appeared. Started from onResume, it
  was still pending when the launcher finished resuming, and Quickstep cancels any
  pending request at that point. It now starts from onDeferredResumed, after that
  check, through Launcher3's own ApiWrapper.assignDefaultHomeRole.

Updater
- An automatic check that fails (phone offline, say) no longer leaves "couldn't reach
  the update server" on the About screen. The screen keeps what it showed before, and
  the check runs again in an hour. A check started by hand still reports the failure.

Checked on the Android 17 emulator with the 0.2.0 release build made before this commit:
swipe up and hold in gesture and in three-button navigation, the list darkening under
a wave that reaches in from the right edge, and the work profile tabs. The two changes
in this commit are not yet checked.
