Jon Snow was acclaimed as King in the North, not as Lord of Winterfell. This is just like hat happened to Robb Stark in season 1, election by acclamation was a common practice in history until the kings started associating sons to their thrones while they were alive (i.e. having them elected king along with them so that they could succeed them). And, although they ere king and obetained the loyalties of their subjects, they didn't inherit any lands or titles along with their election.

Therefore, Jon may be the King in the North, but he is still a bastard of House Stark. Until Bran returns, Sansa is officially the Lady of Winterfell and the head of House Stark.
