DATAMONGO-1721 - Polishing.

Removed deprecated types and adapt dependency tests accordingly.

Refactored MongoExampleMapper to revert to use StringMatcher from Spring Data Commons' ExampleMatcher. Introduced MongoRegexCreator specific MatchMode, which is basically a copy of StringMatcher. Adapted MongoExampleMapper and MongoQueryCreator to translate from StringMatcher and Part.Type to MatchMode.

Turned unit tests for MongoRegexCreator into parameterized ones.
