User listing errors when deleting a role

[mefutu01]

Description

After enabling groups and roles. I created some users with standard roles. Then, I thought I needed completely different user role settings and deleted the ones I didn't need. Some of the users ended up with "irrelevant" roles.

After, I try to change the user on the /users//edit page. I can't do it, because of an error
Call to a member function permissions() on null.

Steps to reproduce

Create a user with a role. Delete a role. Try to load the user listing.

Expected result

I expect that not having a remote role will not throw an error

Actual result

message 'Attempt to read property "name" on null' exception "ErrorException" file "src\\Http\\Controllers\\Admin\\UserController.php" line 143
