Genome::Model::Tools::Htseq::Count v2

Fixes bug reported in RT/98157 and defined new result as v2.  The only
change is in the _htseq_stranded_param so methods version by
Genome::Command::WithSavedResults are just aliased to v1.
bump default version of Htseq::Count to v2

Since v1 produces bad results the default should be bumped to v2.
