[BUGFIX] Require `jquery` before using it when rendering ckeditor

In rare cases it might occur that jquery is not available on ckeditor
initialization, but it's used already. Interesting is that jquery
is explicitly required two lines later.

The code is now changed to require jquery before using its document.ready()
handling.
