t: do not hide Git's exit code in tests using 'nul_to_q'

Git should not be on the left-hand side of a pipe, because it hides the exit
code, and we want to make sure git does not fail.

Fix all invocations of 'nul_to_q' (defined in /t/test-lib-functions.sh) using
this pattern. There is one more occurrence of the pattern in t9010-svn-fe.sh
which is too evolved to change it easily.

All remaining test code that does not adhere to the pattern can be found with
the following command:
git grep -E 'git.*[^|]\|($|[^|])'
