[BUGFIX] Get the functional tests to work with TYPO3 >= 12.1 (#704)

Starting with TYPO3 12.1, a request is required for the
`BackendConfigurationManager` to not crash:
https://review.typo3.org/c/Packages/TYPO3.CMS/+/76447

Also, a fix in that area has been merged (after the release of TYPO3 12.1)
that might allow us to remove our workaround again once we've updated to
TYPO3 12.2 or 12.1.3:
