Material-ui: [Checkbox] disabled={true} causes enormous amount of error messages on react-16

[yhaskell]

Error is caused by those lines:

https://github.com/callemall/material-ui/blob/332c1dfdf5baf8861f3dba05995ef4c1a5e78bc2/src/internal/EnhancedSwitch.js#L348-L352

Error I'm getting is as follows:

proxyConsole.js:54 Warning: Expected `onTouchEnd` listener to be a function, instead got a value of `boolean` type.

@yhaskell This is a good catch. Do you want to submit a PR to fix it? :)

I'm working on a PR for this.
