[android, intent] Run restoreContentForGame for shortcut launching + Improve custom settings context for shortcut launching (based on normal launch) (#3854)

intended to fix two bugs identified by Pavel upon android shortcut launching (and prolly all FEs since the rely on intent launching too):
1. external content not loading: fixed by running restoreContentForGame  for per game mount in content path.
2. custom settings no loading: that was proven to be user side, but adjustments were made to match normal launch.
should be harmless for normal usage. once validated can be merged.
