[BUGFIX] Use DataHandler->log consistently

When using DataHandler->log, the format changed
to using an associative array as $data, whereas
the message then contains PSR-3 compatible log
strings.

This was handled in TYPO3 v12 but a few
places around Workspaces were missed.

This patch adapts these places.
