Improve Find Query for Index Ranges (make clause for Deflector Indices more explicit, etc.)

[janheise]

Description

If you have an index that has messages with a timestamp 1970-01-01 00:00 but that has already been rotated (index_range has begin == 0 and end != 0), it was still found as a valid index for certain operations by the former, now changed query clause that was supposed to only find deflector indices (begin == 0 and end == 0).

This PR fixes the query clause.

I added more tests to reflect those situations.

Also, if you query with a end time before begin time now, an exception is thrown because of an invalid time range.
