Blake/rna 389 validate all usages of rnc sequence regions in the piepline

[blakesweeney]

I think this updates all queries we want only the active coordinates from querying rnc_sequence_regions to rnc_sequence_regions_active. Not sure if I missed anything, but hopefully it doesn't cause any problems. I also delete a couple files which I think are unused.

• files/crs/fetch-rfam.sql and files/crs/fetch-rnacentral.sql, not sure they are needed or not. I made the change anyway. We haven't imported CRS in a while, maybe we should fix that, so I think it is ok.
• I think I already changed files/ftp-export/genome_coordinates/query.sql.
• files/import-data/evlncrnas/dump-lookup.sql has a lot of commented out code where it appears. I removed the commented out code.
• files/import-data/post-release/002__Cleanup_assembly_table.sql - I'm going to leave this one. I think we should stop removing assemblies like this and you have done some work to allow multiple assemblies per species.

The repeats is fine, this isn't used but needs to be finished properly.

The evlncrna code probably shouldn't fetch regions. We generally don't import regions from the databases which are imported by reference. Also, that file has a bunch of commented out code that should be removed.
