Typo
First pass at not clearing user-persistent cookies

This attempts to fix Privacy Badger inadvertently deleting
cookies that the user adds as exceptions to "Clear all
cookies when browser exits." We guess that if a cookie is
in userGreen, the user wants it to persist between browser
restarts if they've set all cookies to be session cookies
by default.
