Fix System tests that rely on UID1's super user behavior

Left comments on MR.

Left more feedback.

Also @pradhumanjain2311 why did you just remove $usesSuperUserAccessPolicy but not try and fix any of the tests? Not saving credit for that. Please if going to work on these try and fix them.

The scope of the tickets are to just add permissions for the logged in users.

Adding additional assertions is out of scope and definitely shouldn’t be updating the performance test as nothing here should impact that.

- reverted performance tests. worked now. looks like it was a random error in test the first time
- removed one extra assert
- keeping one assertion. If this assert is removed and the permission 'administer account settings', is also removed, the test passes but it would not be correct since the page that opens is access denied which doesn't have local tasks.

A follow up should then be opened for expanding test coverage. Should stick within the scope of the ticket please

Will fix later changing to permissionless seems to be changing what's tested.

All I did was some cleanup, still green

Now that user 1 is no longer special we can make the kernel tests much nicer here...
