distclean claims FLAVORS not supported when they are

[khera]

Prerequisites

• Have you checked for an existing issue describing your problem?
• Are you running the latest version?
• Is your ports tree recent?
• Is your FreeBSD Host on a supported release?

Describe the bug

Running `distclean` complains that the tree does not support FLAVORS even though it does

How to reproduce

Create a port-list file including devel/git@lite

Run

poudriere distclean -f /usr/local/etc/poudriere.d/port-list

The output errors with:

[00:00:03] Loading MOVED for /usr/local/poudriere/ports/default
[00:00:04] Gathering all expected distfiles for ports tree 'default'
[00:00:04] Error: Trying to build FLAVOR-specific devel/git@lite but ports tree has no FLAVORS support.
[00:00:04] Error: Trying to build FLAVOR-specific editors/emacs@nox but ports tree has no FLAVORS support
.
[00:00:04] Error: Fatal errors encountered gathering distfiles metadata
Exiting with status 1

Note that when running bulk it confirms that FLAVORS is supported, and is able to successfully build the flavor devel/git@lite.

Expected behavior

I expect the distclean to complete its job.

Thanks for your report. I'll be sure to get a fix into the next minor release. I don't have time to investigate it at the moment.
