Updating team member roles fails

When adjusting a team members role (ex. viewer > editor), Delvin will display a message that the update has been successful. However, the team member's role will not have changed. It does not display the new role in the member list, nor will the member have the updated permissions.

Steps to Reproduce User 1

1. Log in
2. Create a new workspace.
3. Click Team.
4. Click + New Member
5. Add new member as a viewer

User 2

1. Validate User 2 account
2. Log in as User 2 in a separate tab
3. Navigate to shared workspace

User 1

1. Adjust User 2's permissions from viewer to editor.

The success message indicating that a User 2's role was change, but the role in the Team Member list is not changed.
