Relations were inserted by TYPO3's DataHandler after indexing and were
therefore not indexed.
We now use a later hook after DataHandler has finished everything, so we
know that we can index. As it's not relevant, we do not differentiate
between add and update anymore, as both trigger "indexDocument" internal.
Resolves: #112
* Add typoscript option which TYPO3 tables should be processed and which
should not be processed.
* Respect new optiion in hook.
* Also add necessary tests.
* Remove old no longer needed tests for hook.
* As introduces through review, the tests are working and have huge code
coverage, but don't test what they say. Therefore we reorder them in
new structure, to have new tests in clean structure.
* FEATURE: Added tests for hook and implemented logic
* To enable updating search index on modifications through TYPO3 API.
* BUGFIX: Fix path for unit test coverage report
* To fix failing delivery to scrutinizer.
