[v5,5/7] tests: don't swallow Git errors upstream of pipes

Commit Message

Matthew DeVore Oct. 5, 2018, 9:54 p.m. UTC 
Some pipes in tests lose the exit code of git processes, which can mask
unexpected behavior like crashes. Split these pipes up so that git
commands are only at the end of pipes rather than the beginning or
middle.

The violations fixed in this patch were found in the process of fixing
pipe placement in a prior patch.
