Determines, whether current source content requires reconnect of the backend.
It is optional to implement this virtual method by the descendant. The default implementation compares e_source_extension_authentication and e_source_extension_webdav_backend, if existing in the source, with the values after the last successful connect and returns true when they changed. It always return true when there was no successful connect done yet.
