User selection in group editing has an api call for each selection - SP 0.5

[georgimld]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Each time a user is selected or deselected using the checkbox in the dialog, an api call for group.addUser or group.removeUser is bein sent.

Expected Behavior 🤔

Users to be added and removed should be stored (e.g. in an array), and the requests should only be sent when clicking the "Done" button.

Steps to Reproduce 🕹

Steps:

1. open the edit dialog of a group
2. click on the dropdown for selecting users
3. try to select or deselect users and look at what calls are being sent
