[OCIS] [spaces] delete dialog box is not cleared from screen while trying to empty the trashbin if the user doesn't have enough permission to do so

[SwikritiT]

Steps to reproduce

1. As space admin "Einstein" create space "team.1" and add user "Moss" with role "viewer"
2. As user "Einstein" create file parent/test.txt and delete test.txt
3. As user "Moss" go to trashbin of team.1 , you can see deleted file test.txt
4. Now click the Empty trash bin button, a dialog appears then click delete

Expected behaviour

An error message Failed to delete all files permanently appears on the screen and the dialog box should be cleared

Actual behaviour

An error message Failed to delete all files permanently appears on the screen but the dialog box is not cleared. This problem only exists when the deletion is done through Empty trash bin button, when selecting the resources one by one and clicking delete the dialog box is cleared. Also if the user has enough permission to delete the files, the files are deleted and the dialog box is cleared.
