No arity warning when linting ubergraph 0.6.0

[jafingerhut]

I found one manually that Eastwood did not catch. It is the get-edge call on this line of version 0.6.0 of the code:

https://github.com/Engelberg/ubergraph/blob/v0.6.0/src/ubergraph/core.clj#L188

I haven't yet investigated why it failed to catch this. Does the called function being private have anything to do with it? Or that the call is inside of this def-map-type macro?
