Adjust for PrimaryKey session.

[dereuromark]

Resolves #123

Also cleaned up PHPStan and CS.

With this it actually works out of the box for me with the new Auth plugin and PrimaryKeySession:
https://github.com/dereuromark/cakephp-tinyauth/blob/master/src/Authenticator/PrimaryKeySessionAuthenticator.php

For me all tests pass locally.

The change is fine, just need test coverage for the new option

[dereuromark]

It doesnt look like it has any such tests yet regarding user table access, neither with array or Entity.
As such I tried to add specifically for id case, but I cannot even get passed the getUser() missing from the Table, since there was also never a callback test or so.

I wonder how to best achieve this given these circumstances.

[dereuromark]

Tried this
dereuromark/cakephp-social-auth@master...dereuromark:cakephp-social-auth:tests

And I can see it being in the session correctly before the middleware redirects
But the test case itself doesn't reflect that for some reason

ping @ADmad
I can confirm that it works
