Fix 'No Apps' UI issues of ManageApplications

Fixes below UI issues

- "No Apps" may not show in fragments of profile tab.

  Fix it by using ConstraintLayout to specify alignments
  of each view and removing extra padding.

-- "No Apps" may flicker by moving position.

  The flicker is from unnecessary visibility changes.
  This change integrates empty view visibility
  control in LoadingViewController to simplify code
  and avoid unnecessary visibility changes.
