* added failing test case
* add date conversion for geoNear query
- geoNear stages were not parsed for date fields, but mongodb nodejs adapter requires date object
* reverted unnecessary code auto-formatting
* limited parsing to query property of geoNear stage
- the geoNear object contains parameter keys which could be identical to field names in the collection, which should not be parsed and changed, therefore restricting parsing only to query parameter key
* reverted unnecessary code auto-formatting
* added index type parameter to ensureIndex
- required to create geo index for geoNear test
* added geo index creation to test case
* fixed dates in test case
- test case likey failed due to date rounding
* added error output to console
- temporary, to find out why test fails on mongodb 3.6.9
* create seperate class to avoid multiple geo indices on TestObject class
- mongodb <4.0 does not allow nultiple geo indices on a class when using geoNear
- see https://docs.mongodb.com/v3.6/reference/operator/aggregation/geoNear/#behavior
* fixed incorrect result validation
- results were not ordered properly, so test validation failed sometimes
* removed error output to console
