[5.5] Revert #22649

[timoschwarzer]

That commit caused unit tests using the actingAs helper to fail

[sisve]

It would be nice to have a tests for actingAs so it doesn't fail again.

[crynobone]

I would actually opt for fixing actingAs() instead of doing this.

[taylorotwell]

How exactly did it cause it to fail. We need more information?

[timoschwarzer]

@taylorotwell the actingAs helper called setRequest which has set the user to null again.

[vlakoff]

Refs #22817 that has subsequently added tests for this.

[crynobone]

Should note the added tests doesn't break with and without the "broken" changes. I don't have enough information to replicate the issues.

In the other thread it does mention that request is being rebind before call() is being made but auth service provider already cover these scenarios.

If anyone want to properly prevent such issues, need to further improve the test. Otherwise same thing can happen again, since tests is green.
