 [13139] made a number of changes to standardise the the values returned by
 the options API. However add_option() will still return null when the
 option already exists. This should be changed to `return false` and the
 @return docs updated.

 I then also spotted a difference in the behaviour of add_option() vs.
 add_site_option(). add_option() will just stop if the option already
 exists, see above, but add_site_option() will call update_site_option().

 On singlesite installs add_site_option() is just a wrapper for
 add_option() so calling add_site_option() has different behaviour on
 multisite vs. singlesite.
