this has the potential to remove a launch entry for a different chrome than the
one being uninstalled.  it's safer to only remove it if the path matches the
chrome being uninstalled.  here's one way it could do the wrong thing:
1. user has a pre-existing user-level chrome install
2. system-level chrome is magically installed on the machine
3. user runs system-level chrome and sets it to launch at login
4. user runs user-level chrome, which notices the existence of system-level and
self-destructs (it runs its own uninstaller)
5. user-level chrome's uninstaller nukes the user's auto-launch entry for the
system-level chrome
6. user no longer has the auto-launch love

this issue will be resolved if you take my advice and make WillLaunchAtLogin()
take the path to a Chrome, and only return true if that Chrome will launch at
login.
