Bowtie2 data-manager put a wrong path in the loc table

[lldelisle]

Hi,

Using the last version of the bowtie2 data-manager prevented me using the newly created indexes:

In the table, the entries are like:

mm10	mm10	Mouse (mm10)	/depot/data2/galaxy/mm10/bowtie2/mm10.fa

instead of

mm10	mm10	Mouse (mm10)	/depot/data2/galaxy/mm10/bowtie2/mm10

The indexing worked well I think it is just the table that is not correct because when I removed the .fa from the table I could use the newly generated indexes.

I think the issue was introduced by #6489 and I think here:

https://github.com/galaxyproject/tools-iuc/blob/da2aa10802e960a69f3858f86b858807442ca7c7/data_managers/data_manager_bowtie2_index_builder/data_manager/bowtie2_index_builder.xml#L31

It should be ${value}.
