The reason why quote reply is empty is when quote reply is clicked, it
triggers the click function on `.comment-form-reply` button, and when
the first time this function is triggered, easyMDE for the reply has not
yet initialized, so that click handler of `.quote-reply` button in
`repo-legacy.js` got an `undefined` as easyMDE, and the following lines
which put quoted reply into the easyMDE is not executed.
The workaround in this PR is to pass the replied content to
'.comment-form-reply' button if easyMDE is not yet initialized (quote
reply first clicked) and put the replied content into it the after
easyMDE is created.
Now quote reply on first click:
