TIF: Use per-user ContentResolver in the TvInputManagerService

When switched to a different user (e.g. Restricted profile), the
TvInputManagerService continues to use the TV storage of the previous
user for logging, resulting in failure of the FOREIGN KEY constraint
since channel data for the current user don’t match to the logging data.
This change ensures that the system service uses the proper
ContentResolver when the user is switched.
