only install required lodash functions

This should reduce the install size by a few megabytes.

Im not sure why the build failed ember try ember-release works locally

[mriska]

The error it gives is:
No tests were run, please check whether any errors occurred in the page (ember test --server) and ensure that you have a test launcher (e.g. PhantomJS) enabled.

I have also see this in my projects from time to time. Unfortunately it is indeterministic and does not occur on every test. I am trying to track down the error but have not managed to do so yet.

Restarting the individual Travis build that failed usually results in a non-failing build.

@kimroen Could you try to restart the failing builds and see if they turn green?

[kimroen]

I have actually restarted them once already, but running them again now! 👍

Yay, thank you very much!
