Suppress bad Directory comment when DocumentRoot is not set

[gcoxmoz]

It's valid for a DocumentRoot to be missing (docroot => false).
However, in the directories section, this leads to a confusing message:

## Directories, there should at least be a declaration for false

Closing and reopening to kick off a test.

[gcoxmoz]

My read of the tests that failed suggest these are problems in the tests themselves. If I'm wrong, please reaim me, but mentally I'm considering this as a green run.

[pmcmaw]

Hey @gcoxmoz yes I completely agree. I have pushed a change upstream for the mend tests, therefore I will rekick it and it should pass this time round. The SLES failure I think is transient, I will rekick it too. Apologies I needed to double check it was failing and your PR was the first I came across that was in the specific timescale I needed to test.

[pmcmaw]

Sorry having to close and reopen to kick off the mend tests properly.

[gcoxmoz]

I don't mind being the guineapig here, no apology needed. So long as you see the testfails are not a Me thing, and seems like you do.

[pmcmaw]

Mend failure is unrelated to PR changes.
Merging, thank you for your patience 👍

That was me - woops...
