GEOMESA-128 Copy feature-type UserData within the IndexEntry

One-line fix to ensure that features are inserted with the
feature date-time rather than the current system date-time.
Also added a unit test to ensure that we don't jeopardize
this function in the future.

Wrap dtg variables in core.index in Options, since the temporal field in optional.
Also modify FilterToAccumulo to handle these changes.
