Eval does not stop on the first assertion failure it encouters.
Instead, it tries to evaluate all assertions and returns with a list of
those that failed.
This means our very top `config.mailserver.stateVersion != null`
assertion does not gate against any other assertions trying to compare
null against an integer.
The error prior to this commit can be reproduced by removing
`mailserver.stateVersion = 999;` in tests/lib/config.nix and then trying
to evaluate any of the tests:
~~~bash
# nix eval --raw .#checks.x86_64-linux.internal-unstable
error:
… while evaluating the attribute 'outPath'
at /nix/store/syvnmj3hhckkbncm94kfkbl76qsdqqj3-source/lib/customisation.nix:421:7:

Issue: The dovecot homedir for LDAP users was previously not respecting `mailserver.mailDirectory`.
|
|
Remediation:
|
|
- Stop the `dovecot2.service`
|
|
- Move `/var/vmail/ldap` below your `mailserver.mailDirectory`
|
|
- Increase the `stateVersion` to 2.
|
|
|
