[FIX] web_editor: insert record name as text

Previously, the many2one widget from the web_editor used jQuery's
'.html()' method when inserting a record name into the page. The record
name was not HTML-escaped before this, which may have unexpect result
and break the layout.

This commit fixes that by using the '.text()' method instead.

This bug only affects pages containing a many2one (contact excluded)
at the time of selection and not after the selection.
e.g. on the /event page, changing the category of an existing event
via the website editor
