fix(OData): sorting columns via id instead of field property name, fixes #1467

[zewa666]

As mentioned in #1467 this fixes the OData Service to behave like the Graphql counterpart and store the columns id instead of field property, so that if the resulting gridState is persisted and re-applied, everything works as supposed

fixes #1467

LGTM, will wait for @jr01 review if he has a chance. Thanks

Also just so you know, there's also an Example 15 with OData demo which is a little less busy in terms of demo functionalities, the only difference is that it uses RxJS so it was mainly added to test that part. So if we ever want to add more stuff in the demo, then the Example 15 might be ok too. Cheers
