Pressing enter at the end of a line within a code block throws an error

See behavior below:

I imagine this may be because of the code block having a wrapper: https://github.com/springload/draftail/blob/81de01963c8e0799fc74e30a9ad79272ead05b56/lib/api/behavior.js#L37-L41

This might not be compatible with how draftjs-utils handles newlines: https://github.com/jpuri/draftjs-utils/blob/0ca605084a64a0fddb62d680918aad4bea1400a2/js/keyPress.js#L63

This isn't related to the block having a wrapper, this is because of how tryToRemoveBlockStyle from Draft.js is used. Corresponding draftjs-utils issue: jpuri/draftjs-utils#10.
