Call to a member function isAdmin() on null” when trying to install the Panel

[texnixe]

Describe the bug
When trying to install the first Panel user, after clicking on "Install", the above mentioned error message appears and it is not possible to install the first user.

To Reproduce
Steps to reproduce the behavior:

1. Download a fresh 3.2.1 Starterkit
2. Go to yourdomain.com/panel
3. Enter credentials for the first user
4. Click on "Install"
5. See error

It's caused in this line:

 if ($role === 'admin' && $user->kirby()->user()->isAdmin() === false) {

Should probably be

 if ($role === 'admin' && $user->isAdmin() === false) {

Expected behavior
The first user should be installed without error.

Tried to reinstall my plainkit with v3.2.1 and got the same error.

Tested your fix and it worked in file kirby/src/Cms/UserRules.php.

I'm really sorry for this :( That's my fault.
The fix looks a bit different though. I just created a new branch for it: https://github.com/getkirby/kirby/tree/release/3.2.2

Please give it a try and let me know if this fixes it for you as well.
We will launch it later today.

I replaced the lines with the new code from the branch and deleted my previously created user. After accessing the panel again, I was successfully able to create a new user. Seems to work!
