Following up on r1557207 and r1582023, explicitly handle incomming
last_change_* values from the main update request even when not in
send-all mode.

This resolves an assertion that is reproducable by

$ svn co http://svn.webdav.org/repos/projects/neon/trunk neon -r 0 \
      --config-option servers:global:http-bulk-updates=false

* subversion/libsvn_ra_serf/update.c
  (report_state_e): Enable the special property values added
    in r1582023.
  (update_ttable): Enable entry prop transitions.
  (update_closed): Directly forward these properties to the file/directory.
