Ensure CallerInfoAsyncQuery uses HSUM aware method to check user id of current process.

CallerInfoAsyncQuery#getCurrentProfileContentResolver was using a deprecated non HSUM aware method in order to check the user id of the current process. This was causing some contacts provider UT to fail when the device is HSUM mode. This CL updates CallerInfoAsyncQuery to use the HSUM aware reccomended method UserHandle#myUserId instead.
