fix: RemoveArgs only remove the first occurence of an argument

Make sure we remove all the occurence of the passed argument

This fix profile loading not working correctly when there are two occurence of iwad, one passed through command line and another from the profile commandline.txt if the cvar cmdlineprofile is set before starting the game
