[Quotes] Linebreak not behaving as expected on exiting quote

[artcodespace]

Seen in the example app on 18 Jan.

Steps to reproduce:

• write some text (perhaps not necessary)
• click the quote button
• write some text
• press enter (note same issue as code blocks where cursor does not appear to move, raised in issue [Code blocks] [Quotes] Enter does not appear to move cursor to new line #491)
• note that linebreak appears inside the blockquote tag
• press enter again to stop editing the quote
• cursor moves outside the codeblock (good) but linebreak moves from inside the blockquote to the containing element

Expected behaviour:

• On second press of the enter key I think that the blockquote should have the final br node removed
• The cursor is then placed after the blockquote

Tested and no longer an issue. We don't use line breaks but paragraphs now and a paragraph is correctly started after the quote.
