[ Impact ]

When mounting an external location a script is used to get the current default app for a type, its return error is parsed by the dock to provide users a feedback, but the returned code is not valid in case of error.

[ Test case ]

Run:
  gjs -m /<email address hidden>/locationsWorker.js /foo/bar/baz
  echo $?

An error should be shown and the return code should be 15

Doing instead

  gjs -m /<email address hidden>/locationsWorker.js $HOME
  echo $?

The file manager desktop-id should be printed and the script should return 0.

[ Regression Potential ]

Some locations may not have a default handler and so not being launched
