2/ Make One handed mode support multiple user switch

Previously OHM did not support for multile user switch.
We get current user id in settings and get/put settings value
with currentUserId.

Test: manual switch user and check Settings > System > Gesture > One-Handed
Test: make RunSettingsRoboTests -j40
