[CaseInE Preferences] Bad URL
When we set a bad URL for the CaseInE server, and we want to do something just after <push, pull,...>, the message is not clear for the user.
Add a clear message to propose a solution:
"Bad URL, Set a valid URL in the CaseInE Preferences page"
<<Possible to add a link to the page?>>
