Reduce Cyclomatic Complexity in Problem Methods

[okolesnyk]

After attempt of adding PHPMD's to check our code some classes were refactored to reduce Cyclomatic Complexity, but some had a @supressWarnings tag added to them.

AC:

1. Reduce the Cyclomatic Complexity to <=10 in the following methods:

    - OperationDefinitionObjectHandler::initDataDefinitions()
    - OperationDataArrayResolver::resolveOperationDataArray()
   

Note:
Do not worry about TestGenerator.php, as we have a different issue to completely refactoring its use.

Closed because this was already addressed by PR #318 and other cyclomatic complexity violations have been addressed by @soumyau
