Minor performance improvements to NullToEmptyCollection/Map #742

I checked the implementation and found that NullsAsEmptyProvider simply calls valueDeserializer.getEmptyValue, so there was no need to specifically wrap it. https://github.com/FasterXML/jackson-databind/blob/15fa6ec14608790664f214ab53688b68aad23dbd/src/main/java/com/fasterxml/jackson/databind/deser/impl/NullsAsEmptyProvider.java#L30

Skipping this process will improve performance, albeit slightly.
