Error in top.sls: Specified SLS 'minions.git01' is not available

Applying states on git machines fails because some pillar data fails to compile:

git01:
    Data failed to compile:
----------
    Pillar failed to render with the following messages:
----------
    Specified SLS 'minions.git01' in environment 'base' is not available on the salt master

This error is triggered by the following configuration:

    - core
  git01:
    - minions.git01
  salt01:
    - minions.salt01

minions.git01 was not removed from top.sls as part of #5 (closed) so top.sls is attempting to find a non-existent pillar file.
