When syncprov updates its local contextCSN value after some modification took
place this update will not be propagated to consumers that doesn't receive the
updated entry (it could fail to match the filter, or access control could
prevent it).  In this case, the consumer will have an old contextCSN value
although its content is up to date.

The provider should in this case send a newcookie sync info message to the
consumer with its updated contextCSN value.  A patch that implements this is
coming.  This patch is required for the new test058 to succeed.
