Issues/initial message params

The final two parameters for the setInitialMessage and setCapturingMessage methods aren't being taken because the argument index is wrong. (Looks like a copy-paste error.) This PR fixes the argument indexes so they are pulled correctly from the Cordova command.

@tbehera @DiegoArenaOlivera Any chance this can be fixed? I don't mind running my own fork but I'm guessing other users may be running into this.

@tbehera - I think this is already fixed?

As of now, master is still showing the argument indices that aren't correct:
