fix(connect): add missing randomBytes import and rename parseGoogleState (#211)

randomBytes was used in generateState() without being imported from
crypto, causing a ReferenceError crash on any GET /connect/github request.
Also renamed parseGoogleState to parseOAuthState since the function is
exclusively used in the GitHub connect flow — Google connect does not
exist in this file.

Closes #178
