fix(Schematics): update upsert blueprint

[timdeschryver]

Closes #1039

Changed the payload of the upsert actions to have a fully qualified entity, see a0f45ff for the change.
I think this is the only change that needs to happen, if not I'll update accordingly.
This is the new (actions) output:

import { Update } from '@ngrx/entity';
import { Foo } from '../models/foo.model';

export enum FooActionTypes {
  LoadFoos = '[Foo] Load Foos',
  AddFoo = '[Foo] Add Foo',
  UpsertFoo = '[Foo] Upsert Foo',
  AddFoos = '[Foo] Add Foos',
  UpsertFoos = '[Foo] Upsert Foos',
  UpdateFoo = '[Foo] Update Foo',
  UpdateFoos = '[Foo] Update Foos',
  DeleteFoo = '[Foo] Delete Foo',
  DeleteFoos = '[Foo] Delete Foos',
  ClearFoos = '[Foo] Clear Foos'
}

export class LoadFoos implements Action {
  readonly type = FooActionTypes.LoadFoos;

  constructor(public payload: { foos: Foo[] }) {}
}

export class AddFoo implements Action {
  readonly type = FooActionTypes.AddFoo;

  constructor(public payload: { foo: Foo }) {}
}

export class UpsertFoo implements Action {
  readonly type = FooActionTypes.UpsertFoo;

  constructor(public payload: { foo: Foo }) {}
}

export class AddFoos implements Action {
  readonly type = FooActionTypes.AddFoos;

  constructor(public payload: { foos: Foo[] }) {}
}

export class UpsertFoos implements Action {
  readonly type = FooActionTypes.UpsertFoos;

  constructor(public payload: { foos: Foo[] }) {}
}

export class UpdateFoo implements Action {
  readonly type = FooActionTypes.UpdateFoo;

  constructor(public payload: { foo: Update<Foo> }) {}
}

export class UpdateFoos implements Action {
  readonly type = FooActionTypes.UpdateFoos;

  constructor(public payload: { foos: Update<Foo>[] }) {}
}

export class DeleteFoo implements Action {
  readonly type = FooActionTypes.DeleteFoo;

  constructor(public payload: { id: string }) {}
}

export class DeleteFoos implements Action {
  readonly type = FooActionTypes.DeleteFoos;

  constructor(public payload: { ids: string[] }) {}
}

export class ClearFoos implements Action {
  readonly type = FooActionTypes.ClearFoos;
}

export type FooActions =
 LoadFoos
 | AddFoo
 | UpsertFoo
 | AddFoos
 | UpsertFoos
 | UpdateFoo
 | UpdateFoos
 | DeleteFoo
 | DeleteFoos
 | ClearFoos;
