> Fix spurious profile shortcuts created with a system-level install.
> 
> This issue was caused by RenameChromeDesktopShortcutForProfile()
> having logic to copy a system-level shortcut to make a user-level
> shortcut in the case where a non-profile Chrome shortcut would
> need to become a profile shortcut (i.e. the first user's profile
> shortcut when creating a second user).
> 
> This path was being triggered by the initial change of the profile
> avatar when the profile was created. The fix is to not to try
> updating profile shortcuts on name/avatar changes when we know the
> profile never had a shortcut created (by virtue of the shortcut
> name never getting stored).
> 
> BUG=177047
> TEST=On a system-level install, create a new profile with the "create
> shortcut" checkbox unchecked. A shortcut should not be created. Change
> the profile's name or icon. The shortcut should still not appear.
