Tests failing on master

[Johan Parin]

In order to be able to run some tests and since OS X Mojave only has
bash 3.2, I installed a Kali vm, downloaded a fresh notmuch repo,
installed the dependencies and did make test. Result:

1123/1128 tests passed.
3 broken tests failed as expected.
2 tests failed.

Can anyone confirm / deny that this should occur on master?

I looked at the tests/README and installed the prerequisite packages,
and also downloaded the test databases.
