Avoid warning about PID file being overwritten on each start of Apache.

This had two causes: first, if "-i", "-u" or "-S" was given (none of which
start a daemon) the PID file was being updated with the new PID. Secondly,
doing "net stop apache" or stopping Apache from the SCM did not remove the
PID file because reporting a STOPPED status to the SCM seems to stop the
process, so move the reporting of the STOPPED service to the very last
thing we do.
