Plugin match incorrect

[Joshua Harlow]

Currently when I have one of the following in
my plugins config:

[horizon-base-plugin-XYZ]

This causes 'base' to think this is a plugin for
it when its only a plugin for horizon (or other
project) which is wrong and causes errors like:

ERROR:kolla.image.build:Unhandled error when running BuildTask(base)
Traceback (most recent call last):
