Don't apply babel-plugin-transform-runtime inside react-on-rails to work with babel@7

It should be applied by user land.

Why?
The generated code depends on built babel's version.
It means that user couldn' build their code with babel@7 that depends on react-on-rails built by babel@6.

For example, babel-plugin-transform-runtime (babel 6) generates the
following code.

var _assign = require('babel-runtime/core-js/object/assign');

However @babel/plugin-transform-runtime (babel 7) expects the
path that beginning of @babel/runtime/.

The change allows to use react-on-rails on babel@7.

…ils to work with babel@7 (shakacode#1136)"

This reverts commit de06717.

In general, Webpack doesn't build under `node_modules`.
So react-on-rails should support browser compatible build.

* Revert "Don't apply babel-plugin-transform-runtime inside react-on-rails to work with babel@7 (#1136)"

This reverts commit de06717.

* Specify babel-runtime as dependencies, not as peerDependencies

babel-runtime is not installed Babel 7 environment.
(Babel 7 denpends @babel/runtime.)

So this should be depended as "dependencies".
