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.
Adjust existing code base to not use hardcoded file path.
Instead use info from database and check all files which have references
to event objects.
Also add test to cover feature.
* Add dependency.
* Remove empty tearDown() methods.
* Fix signature of setUp() to be compatible with recent phpunit.
* Temporary fix syntax issues in test files
