MAF tools do not find indexed hg19 46-way or 100-way. CVMFS path problem?

[jennaj]

Found while retesting this fix: #130 (comment)

Test history: https://usegalaxy.org/u/jen/h/test-maf-tools---tool-group-fetch-alignmentssequences

dataset 51: Fatal Error: The MAF source specified (46_WAY_MULTIZ_hg19) appears to be invalid.
dataset 50: Fatal Error: The MAF source specified (100_WAY_MULTIZ_v2_hg19) appears to be invalid.

@natefoo @davebx - Paths in CVMFS changed. Maybe these were missed when others fixed?

Many involve MAF tools, not just data. Some might be resolved, needs an update.

My favorite construct: catch exceptions and silently ignore them.

AttributeError: 'SeekableLzopFile' object has no attribute 'readable'

I think SeekableLzopFile needs to implement io.IOBase?

Combined with lack of testing it's a thing of beauty!
