Extends PR #3460, also locks immutable version

[jkomyno]

The main purpose of this PR is to add the same logic that PR #3460 (which was merged) added to onChange also to onBlur and onFocus.

I've also edited a dev-dependecy line of package.json:

-"immutable": "^4.0.0-rc.3",
+"immutable": "4.0.0-rc.3",

This was necessary to prevent the test suite to fail miserably with 21 errors (all of them are immutable-related). This isn't a solution to #3493, but it's needed to mark the fact that versions 4.0.0-rc.>3 of immutable aren't supported as of now. I hope this doesn't add to much noise to the PR @erikras.
