The logic behind is:
1. Tizen app ID != Crosswalk app ID
2. currently launcher uses symbol link of Crosswalk app ID
3. if we want launcher cmdline has proper name there're 2 ways to do it:
  a. change the argv to Tizen app ID
  b. change the symbol link to Tizen app ID

I prefer the method <b>. The Tizen app ID generation function is just copied from old code.
