changegroup: call 'prechangegroup' hook before setting up write delay

The 'prechangegroup' interfere with 'delayupdate' logic because it trigger the
one time call of 'changelog._writepending' (see issure4934). There is no reason
not to call that hook before setting up 'delayupdate' so we move the call a bit
earlier to avoid interference.

    traceback.print_stack(args[1], limit=10, file=sys.stderr)
    sys.stderr.write("----\n")
