Enter key deletes single list item in a list, but leaves empty list

Type of report

Bug

Provide detailed reproduction steps (if any)

1. Enter https://nightly.ckeditor.com/basic/samples/
2. Set data with developer tools

CKEDITOR.instances.editor.setData('<ul><li><br/></li></ul>')

3. Place cursor manually inside empty list item

<ul><li><br/>^</li></ul>

4. Press enter

Expected result

<p><br/></p>

Contents of li element are moved in a new node, and ul node is removed, because it's empty now and we don't need it anymore. Maybe it should have the same behaviour as when backspace is pressed?

Actual result

<p><br/></p><ul></ul>

UL tag stays in dom.

I thought it may be a regression introduced in #2205 but it's not. There is no need to use a code to reproduce the issue, you can just add an empty list and press enter - a list still exists in the source code, but should be removed entirely.
