    gs-details-page: Show "Pending installation..." on "Install" click in offline
    
    When using "Install" button in offline, the app has only set "queued for install"
    state, but no plugin action, which causes the "Install" button turn into a "Cancel"
    button, with no explanation. The next gnome-software start the "Cancel" button
    has also "Pending installation..." label shown under itself. This change makes
    the label visible also when the plugin action is unknown.
