[Panlingual] Improve conditions of supporting app locale.

 There are 3 conditions we need to check.
  1. Has locale config file
  2. Has locale config file w/o content
  3. Has locale config file w/ content

 Currently, we do not have condition 2 into the condition group, and we
 need to add it into.
