When you remove the user from the group that shared the dashboard with, user will not be able to edit their own dashboard

Steps to reproduce :

• Create a dashboard
• Share the dashboard with a specific group that you are a member of.
• Login as Administrator, remove the user that shared the dashboard from the group they share it with.
• User will be able to see his dashboard but can't edit it.

Expected :

• User still be able to edit his dashboard since they are the owner of the dashboard.

Workaround :

• Login as the sysadmin user
• Navigate to System> Shared dashboards and search for the dashboard that the user is not able to access
• Now click on the gear icon and then "Change Owner"
• Change the dashboard ownership to another administrator user. You will only be able to pick a user that is member of all the groups that the dashboard is shared with.
• Now check if the new owner is able to edit the dashboard
• After this, login with the new dashboard owner and change the shares of the dashboard to only include the groups/roles that the original user is member of.
• Now change the owner of the dashboard back to the original user. The user should now be able to edit the dashboard.
