Generated REST URL invalid when the page name contains ;

Steps to reproduce:

1. Create a page named "Weird; Reference".
2. Inspect the HTML and copy the value of the data-xwiki-rest-url attribute of the HTML element.
3. Open the copied URL.

Expected result:

The document is returned by the REST API.

Actual result:

An error that the document isn't found is displayed.

This is because the URL in the attribute is /xwiki/rest/wikis/xwiki/spaces/Weird;%20Reference/pages/WebHome while it should be /xwiki/rest/wikis/xwiki/spaces/Weird%3B%20Reference/pages/WebHome/requiredRights.

When opening the correct URL, also all URLs in the XML are wrong apart from the self reference:
