[PATCH 3/5] test: Break on test script (or other) error

[Michal Sojka <sojkam1@fel.cvut.cz>]

Break notmuch-test whenever a test script returns non-zero status.
This happens either when some test from the script fails or when there
is an error in the script.

This is especially useful in the latter case since the error may not
appear in the final aggregated results.
