Cannot use `@Property({ name })`, `@PartitionKey()` and `@GSISortKey(index)` together

[nolde]

Describe the bug It is impossible to use @PartitionKey({ name: 'someOtherName' }), @PartitionKey and @GSISortKey decorators alongside each other, as dynamo-easy complains about the lack of primary key identifier.

To Reproduce Steps to reproduce the behavior:

// ...
class CoolModel {
  // ...
  @PartitionKey()
  @GSISortKey('gsiName')
  @Property({ name: 'entity' })
  readonly id: string = genid()
  // ...
}

const store = new DynamoStore(CoolModel)
const cool = new CoolModel({ /* ... */ })
store.put(cool).exec()

A code similar to the one above generates the following error:

ValidationException: One or more parameter values were invalid: Missing the key entity in the item

}

Expected behavior The library should track the updated name and act accordingly, regardless of being a key.

Desktop (please complete the following information):

• OS: Windows 10
• node.js 12.13.1
• typecript 3.8.2
• Version 5.6.0

Additional context I've noticed the existence of issue #215 , which seems to be identical to this one. It says it has been released, but I am getting a similar issue... has this been reintroduced?

If I just change id to entity, code immediately works.

I made a mistake in some other part of my code. Sorry.
