Subject: [PATCH] fix issue of duplicate args of wrt-launcher

[Title] fix issue of duplicate args of wrt-launcher
[Issue#] N/A
[Problem] wrt-launcher doesn't handle duplicate arguments, for instance,
         "wrt-launcher -l -l", it will print widget list twice.
[Cause] doesn't check argument before using
[Solution] check whether the argument has already parsed
