Related PR: #962
Required updates:

• Change all occurences like api.query.members, api.consts.members, api.tx.members: members => membership Doesn't seem to be the case, as api.query.members still works.
• api.query.members.membersCreated => api.query.members.nextMemberId
• api.query.members.memberProfile => api.query.members.membershipById
• api.query.members.handles => api.query.members.memberIdByHandle
• api.tx.members.updateProfile => api.tx.members.updateMembership
• UserInfo in extrincis - replaced with "plain" parameters (handle, avatar_uri, about):
  • buyMembership
  • updateMembership
  • addScreenedMember
• @joystream/types:
  • Remove Role, ActorInRole, ActorInRoleSet, UserInfo, CheckedUserInfo (+ search for any imports)
  • Rename Profile to Membership and remove roles field (also fix in all imports)
  • Content working group Lead - add member id (this opens possibility for some optimalizations in Pioneer and CLI)
• Remove any references to InitialMembersBalance (in case there are any)
