Updates TYPO3 Core to 8.7.5

Allow SOAP endpoint to authenticate via session

See merge request !182

Since we call the SOAP endpoint for certain actions
of an authenticated user on extensions.typo3.org
(like registering ext keys) and we do not know
the password at this point any more,
we now include the session id in the SOAP request,
so that TYPO3 will login this user before the SOAP
endpoint is triggered.

In the endpoint, we can then just check if a user is
already logged in and whether the username given
matches the username of the logged in user.

[SECURITY] Fix unauthorized SOAP access

See merge request !174

By having an inverted condition, attackers

commands (like deleting extensions) via SOAP
