Trinity v2.9.1 fails immediately with input collection type "listpaired"

[jennaj]

Tool/version:

• Trinity de novo assembly of RNA-Seq data (Galaxy Version 2.9.1)

Test history (new/clean):

• https://usegalaxy.org/u/jen-galaxyproject/h/test-history-trinity

Tests: pooled/not/both depending on how the tool accepts inputs

1. single dataset = success
2. pair of datasets (two individual datasets) = success
3. pair of datasets collection ("paired") = success
4. dataset list collection ("listpaired") = fail

Known but didn't have a tracking ticket yet.

Prior/closed: #143

@natefoo followup: tests for list-paired and paired collection fastq inputs failed this morning (immediately) at org. all in the same test history, tagged with "nov25" and the collection type (datasets 31-34)

Slightly different that original testing:

3. pair of datasets collection ("paired") = fail (changed: was success in sep/oct)
4. dataset list collection ("listpaired") = fail (unchanged: consistent fail since sep)

Corrected (thank you @natefoo).

Please rerun any previously failed jobs.
