[BUGFIX] Invalid session token on creating content element in admin panel

When creating a new content element in the frontend using the according
button in the "editing" section of the admin panel, the request to the
TYPO3 backend is rejected due to an invalid XSRF session token:

	Validating the security token of this form has failed.
	Please reload the form and submit it again.

The reason is, that the URL after issue #70055 looks like the following
"token=<hash>id=<id>" instead of "token=<hash>&id=<id>" - the id became
part of the XSRF session token.

Resolves: #83719
Releases: master, 8.7, 7.6
