Ensure that the correct `app_id` for Wayland is set. The upstream implementation
uses `QFileInfo::baseName()`[1] which strips everything away after the first dot.
This means that `.foo-wrapped` has an empty `app_id` because `baseName` returns
an empty string in this case.

The patch basically checks whether the program has the form `.foo-wrapped` (i.e. got
wrapped by `makeWrapper`) and if that's the case, `foo` will be the correct `app_id`.
