There is a XEP for this, XEP 237 - Data Sequencing.  It's use with
rosters is documented here:
http://xmpp.org/extensions/xep-0237.html#roster

Unfortunately this XEP is experimental and is likely unsupported by servers.

The common solution to this problem is to reimplement your bot as a
component, and then it can manage its own roster without help from the
server.
