"Invalid compound target: for results: " error when calling state.highstate

[ewdurbin]

When calling state.highstate on any given node, the following log lines appear during execution:

[ERROR   ] Invalid compound target:  for results: 
[ERROR   ] Invalid compound target:  for results: 

We should determine what these are and how to resolve them.

Running sudo salt-call -l debug state.highstate after vagrant sshing into a given node locally should produce output that helps us track this down.
