Test a description beginning with "depends".

See GothenburgBitFactory#733. I don't foresee
this being fixable from bugwarrior but could be worked around in
taskw.

I confirmed that this does pass with ralphbean/taskw#135.

I've also confirmed that it passes with now that I've upgraded to
taskwarrior-2.6.1. It seems that everyone, including myself, who
reproduced this issue in the past was using taskwarrior-2.5.1.
