Each profile (regular and incognito) has its own HostContentSettingsMap. This
is modified for example in ContentSettingSingleRadioGroup and also presented in
the content settings exceptions in chrome://settings. However, the values of
the HCSM are not reflected in the CookieSettings of an incognito session
because a single CookieSettings instance is shared between regular and
incognito mode. This CL fixes that.
