Fix '-u <user id>' handling in 'adb ime enable' and 'adb ime set'

This is a follow up CL to my previous CLs [1][2], which added
'-u <user id>' option to
   adb shell ime enable <ime id>
and
   adb shell ime set <ime id>
respectively.

Those CL had a bug that was introduced during the last round of the
code review when I was addressing a review comment.  As a result,
those two commands simply fail if '-u' or '--user' option is
specified.  With this CL, those we can finally start specifying the
user ID for those two commands.

This CL also fixes a bug that output for
  adb shell ime set -u all <ime id>
are not correctly formatted.

Note that this CL only fixes a bug in debug shell commands. There
should be no user-visible behavior change in end-user use cases.
