Merge pull request #149 from jetstack/munnerz-patch-1

Automatic merge from submit-queue.

Remove references to minikube in Makefile

**What this PR does / why we need it**:

Since #144 has merged, we no longer reference minikube within navigator. Our builds on travis are now failing, as Travis does not have (nor need) minikube. This PR fixes up the Makefile to reflect these latest changes.

**Release note**:
```release-note
NONE
```
