Leiningen refresh dependencies doesn't work if IntelliJ hasn't saved

[cursive-ide]

Since IntelliJ saves in the background, it's not always obvious when this has happened. However the lein integration refresh doesn't work if it hasn't since lein loads the project map from disk and this may not have been updated. Specifically, this fails in a very common use case - user adds or removes a dependency from the project map and hits refresh.
