[BUGFIX] Prevent undefined array key uid and username in FrontendUserAuthentication

[Patta]

Description

Prevents undefined array key uid and username warnings in FrontendUserAuthentication middleware.
Resolves #1012 which blows up the sys_log on every requested login protected page in queue.
Perhaps not the cleanest solution.

I have

• Checked that CGL are followed
• Checked that the Tests are still working
• Added description to CHANGELOG.md (github-handle is optional)
• Added tests for the new code

I have applied the patch (604cc67), but still get the following warnings:

• PHP Warning: Undefined array key "set_id" in /html/typo3/typo3conf/ext/crawler/Classes/Middleware/FrontendUserAuthenticator.php line 119
• PHP Warning: Undefined array key "qid" in /html/typo3/typo3conf/ext/crawler/Classes/Middleware/FrontendUserAuthenticator.php line 119

TYPO3 11.5.29, crawler 11.0.7

Someone (TM) would need to look into this again then.

@derBoogie I also saw these warnings after warming up the cache after deployment, but not on planned crawling tasks. Could you open a new issue?

@tomasnorre this "fix" seems missing in main (v12) branch.
