How to address go get failures due to breaking changes in Go Client?

There was a change in the function signature of Get action in apache/incubator-openwhisk-client-go@72bf712

```
-func (s *ActionService) Get(actionName string) (*Action, *http.Response, error) {
+func (s *ActionService) Get(actionName string, fetchCode bool) (*Action, *http.Response, error) {
```

`fetchCode` was added to determine whether to return function code or not on a `GET` call. This is just one simple change which was breaking `go get`:

```
go get GitHub.com/apache/incubator-openwhisk-wskdeploy
# github.com/apache/incubator-openwhisk-wskdeploy/deployers
go/src/github/apache/incubator-openwhisk-wskdeploy/deployers/servicedeployer.go:1334:44: not enough arguments in call to deployer.Client.Actions.Get
have (string)
want (string, bool)
```

This kind of change wouldn't break `wskdeploy` travis builds as we specify dependencies in `GoDeps` file. How to enforce those dependency versions in `go get`?
