[windows][3.0.0] u1sdtool --quit starts syncdaemon if it is not running

[Roman Yepishev]

STR:

1. Open process explorer, note that ubuntuone-syncdaemon.exe is running.
2. Run u1sdtool.exe --quit, notice that while u1sdtool says that SD is still running, the later has shut down after a short while.
3. Run u1sdtool.exe --quit again (since you are sure SD is still running)

Expected results:
u1sdtool says it SD stopped and SD is indeed not running

Actual results:
SD was stopped, u1sdtool --quit _starts it_ but u1sdtool says that syncdaemon had been stopped.
