TYPO3 8.7 Compatibility

[schliesser]

The extension isn't anymore compatible with TYPO3 8.7 as the dependency injection has been changed in Commit: 94ea0dc

This change is not yet included in the 0.1.5 release/tag, so it's still working with 8.7

Your next release 0.1.6 breaks compatibility to 8.7 because the dependencies aren't injected anymore:

Core: Exception handler (WEB): Uncaught TYPO3 Exception: Call to a member function getRestUrl() on null | Error thrown in file /.../typo3conf/ext/cleverreach/Classes/CleverReach/Api.php in line 57.

The new dependency injection works from TYPO3 9.0 upwards:
