The vendor was renamed from `wrm` to `werkraummedia`.
And the namespace vendor was renamed from `Wrm` to `WerkraumMedia`.
That way all references to PHP classes as well as the package name
itself need to be adjusted.
It is now possible to create "Import" records in TYPO3 system.
Those records can then be imported via two new commands.
There is no need to configure everything within the command itself.
That allows:
* To allow editors to maintain import configuration.
* Have proper labels, description, csh and UI to create import.
It no longer is necessary to copy UIDs,
instead proper wizards from TCA are available to select pages.

The import already worked without category, but triggered a warning.
Tests were extended to always work with category, except in new test
case.
All tests were extended to check for empty logs in the end.
The import now checks whether category should be imported and ignores
further processing if not configured.

TYPO3 scheduler tasks always have a value for console commands.
Region uid will be an empty string if omitted within scheduler task.
We reflect that in our tests and adapt code to not break.
Furthermore tests call only with strings, as that's what TYPO3 does.
