Database not found if the name ends with 2 digits or more, in release 1.0.13

[loraine-gueguen]

The issue is explained here: https://groups.google.com/d/msg/sequenceserver/jVOLbp2XlkQ/ZvAQqspiAwAJ

The database files are the following:
genus-sp_xx32.nhr
genus-sp_xx32.nin
genus-sp_xx32.nog
genus-sp_xx32.nsd
genus-sp_xx32.nsi
genus-sp_xx32.nsq

I have found were the issue comes from: sequenceserver thinks that this is a multipart database whereas it is not, because of the regex used here:

sequenceserver/lib/sequenceserver/database.rb

Line 218 in e25c96a

!(db_name.match(%r{.+/\S+\d{2}$}).nil?)
