bowtie2 index data manager fails if index already exists

[nturaga]

I believe the issue is caused if the genome index is already built or it handles multiple fasta files during index building.

During multiple fasta file index building, if the basename of the index files is the same it fails. ( i'm guessing this should fail). But if the index already exists on the galaxy instance, it should just tell us that it exists and not build the index again..

The error below is because of same index being built again, or simultaneously
