Submitting duplicate BAMs needs to be improved

[ihodes]

cf. https://github.com/hammerlab/cycledash/blob/master/cycledash/bams.py#L34

BAMs should be unique on project_id, uri, not just uri.

A duplicate BAM submission should return HTTP 409 ("conflict") not 400 (as it does now, "malformed request").

I think this must have been addressed as some point, but now I can just re-submit the same BAM again and again and each time it gets a new ID
