Extract appid from AtomCommandLine and remove redundant code

Extract appid from AtomCommandLine and remove redundant code

In prelaunch atom commandLine initialized with |/usr/bin/wrt-loader|.
When actual application is loaded, its command line arguments are
appending to already existing command line parameters. That is the reason
argv[1] is returning appid. Clearing the commandline |argv_| vector in
|atom::AtomCommandLine::Init| before pushing the new command line arguments.

Removed the unused files.
Extract app id from atom command line and parse for base name.
