Create User type in schema

[roiLeo]

We could create an User type like this to better filter on profile:

type User @entity {
  id: ID!
  owned: [NFTEntity!]! @derivedFrom(field: "currentOwner")
  created: [NFTEntity!]! @derivedFrom(field: "issuer")
}

In #19 I was thinking to call it account

but first iteration is commited: ee07f9b

Got some errors here:

<subql-node> ERROR node failed to start AssertionError: Please check entity User with field owned has correct relation with entity NFTEntity

Edit: fixed

new one:

<store> ERROR Having a problem when syncing schema SequelizeDatabaseError: column "issuer_id" does not exist

[vikiival]

Oh NFTEntity should have issuerId instead of issuer
