ECOMPHP-343

* Moved test suite fake invoice id to getTestInvoiceNumber().
* Cleanup getNextInvoiceNumberByDebits. Clarify a lot of strange things that mismatch with expected behaviour.
* Explaining paranoid mode.
* Adds support for larger hops than just +1 incremental id if AFTERSHOP_RESCUE_INVOICE is active.
* PHPstorm apparently adjusted code.
* Added patches for important problems (ECOMPHP-346) with cached getPayment and proper caches.
* Fixed a misplaced deleteflag.
* Removed invoice id error checking in annulPayments (invoice id errors is not applicable there so we no use the API throws instead).
* Added same invoice id error checking on creditPayment as in finalizePayment.
* If tests must be skipped on finalizeWithoutInvoiceId we now clarify WHERE it was skipped.
* proxyTestingsExcluded.php updated.
* Tests also updated with ECOMPHP-346 checks. Also surrounded some methods with skipTest on error 500.
