https_domain wasn't an accurate description. Changed to media-host,
which is what it is and matches the variable name in adminDomainList

admin init isn't loading domain from LS like it should.

the checkout extension clears localStorage if the buyer is on a shared

more updates to thisIsAnAdminSession()

init was using the adminSession function instead of the variable, which
resulted in a extension validation error.
