Remove CKEditor instance on unmount

[R0nd]

Seems to fix the sometimes appearing "Uncaught TypeError: Cannot call method 'unselectable' of null" errors

[R0nd]

Fixed an issue where new or changed event handlers wouldn't register on existing component.

Any update on this. Seeing this issue.

@hafeezpk the PR has never been merged, you can try installing my fork from npm if you want to, the package name is r0nd_react-ckeditor-component

R0nd i did try the package r0nd_react-ckeditor-component. Still seeing the same issue.

@hafeezpk could you post some code? Doesn't reproduce with a trivial case.

I'm just rendering multiple instances of CKEditor. Although the point to note is, manually on the web browser we never see this issue. Using karma (chrome) which automatically launches web browser for functional testing, we see the issue.
