Guest page creation via shortened URL

[petrenkonikita112263]

Prerequisites:

• XWiki instance 14.10+.
• Latest version of URL Shortner Application (Pro) (for date of issue creation v1.2.1).
• Trial license

Step to reproduce:

1. Being logged as XWiki Admin triggers creating a page.
2. At the first window, provide a dummy name with a default template (blank page)
3. In WYSIWYG window where you can provide content, select the "More Actions" icon and select "Get Shortened URL" (do not save the page)
4. Open a new tab and paste the copied URL

Actual result:
You will end with the page that XWikiGuest created.

Expected result:
Nothing happens because the user cannot access the shortened URL during the creation process.

Note:
I discovered this issue accidentally because when I click "Save and View" from step 3, XWiki warns me that the page with the same name already exists (because XWikiGuest created it).

In 1.2.8, the option to 'Get shortened URL' does not appear anymore for pages which were not saved yet.

Can you confirm this is the case? If so, I think this isssue can be closed.
