Wild card usage in Thimble ignores extra genes (-xg/additional-genes.fasta)

[JamieHeather]

Using 'TRAVx*%' in Thimble should produce rows in the output for that rearrangement with all included alleles of TRAVx, however it currently only includes alleles that are included in the appropriate locus' fasta file in the relevant species folder in the data directory.

Not a big issue (as users can just pop their additional genes in those files directly), but it's not expected behaviour and encourages editing files which are best left managed by the automatic downloading of stitchrdl.
