fixes https://github.com/KILTprotocol/ticket/issues/160

This is just replacing constructor calls of refactored constructors and changing property names accordingly.

I'll create a second ticket if we want to change our descriptions aswell hash to roothash and cType to cTypeHash.

Here, we still use a fromObject method:

demo-client/src/components/SelectAttestedClaim/SelectAttestedClaim.tsx

Line 51 in d104e24

this.setState({ cType: CType.fromObject(cType) })

It might be too much for this PR, but this whole ctype class is a big annoyance for me:

demo-client/src/types/Ctype.ts

Line 30 in d104e24

export class CType implements ICType {

My last remarks will be fixed in #231
