Lift a region that overlaps the genomic occurrence of the retrotransposon
to consensus sequence coordinates using just the coordinates (not the full
alignment), when they have differing length. This is an internal helper
method. The above length constraint must be true, otherwise an assertion
is failed.

:param intersect_region: a region that intersects this occurrence.
:return: list of GenomicInterval objects. This is a list because a genomic
         deletion of part of the retrotransposon can fragment the
         intersecting region and result in more than one returned interval.
         List might be empty, if intersection overlaps only gaps.
:note: no checks are made for whether the interval really intersects!!
