Running cordova prepare on projectRoot as cwd.
Running cordova prepare on projectRoot as cwd.

When starting simulation with the dir option to specify the cordova app as cwd, cordova prepare doesn't use projectRoot given by parameters, instead it assumes that the cwd is a cordova project.

Updating cordova prepare command execution to run on the projectRoot as cwd.

This closes #2
