homescreenhandler: Avoid passing an invalid appid

If there's no item added in the QList we'll return an invalid value
pointing to some invalid memory, which we can not determine if its empty
string or not, so this makes sure we check the list itself.

Found when looking at removal/activation of surfaces while re-doing some
parts in the compositor.
