SocialDataImporter: run extracted to new class SocialDataImporterRunner
SdiPropertiesDefault: renamed to SdiMainPropertiesTest and added a new between interface SdiMainProperties, incl. the name of the property file
new class SdiMainPropertiesTest in order to be loaded if started by SocialDataImporterRunner instead of the main SdiMainPropertiesTest
Annotation ConditionalOnMissingClass must specify the FQCN instead of the class (deprecated and not working as expected)
SDI-core/.classpath: output folder for test resources corrected
All converter derivations are now annotated with @Component
Note: The SocialDataImporterRunner fails in the ConverterDate. But the same code with same input succeeds in CsvCollectorTest!!
