Pasting autoembedable link with extra content embeds the link

[Szymon Cofalik]

There are cases when pasting some text with autoemedable links makes editor embed content in their place.

Steps to reproduce:

1. In empty editor type foo bar
2. Place caret between spaces
3. Paste https://instagram.com/p/wZB11CIfqX/ and let it convert.
4. Undo once, so you get foo https://instagram.com/p/wZB11CIfqX/ bar. Mind, that the link is converted to <a> element.
5. Select everything (using mouse or alt+a).
6. Cut and paste.

Expected result: Editor should contain foo https://instagram.com/p/wZB11CIfqX/ bar with the link being <a> element.
Result: The link is converted to embeded object.

Please note, that just pasting: foo https://instagram.com/p/wZB11CIfqX/ bar works correctly - the link is not converted.

This issue seems to have been fixed in CKEditor 4.5.2. I could not reproduce this problem in that version.
