Timeline request returns `paging` as array

[njkleiner]

When making a timeline request for an empty channel, the paging property returned is an empty array, rather than an empty object.

This makes it impossible to parse the response in some circumstances where the paging property is expected to always have the same type (i.e., JSON object).

$ curl -i -H "Authorization: Bearer <redacted>" "https://aperture.p3k.io/microsub/452?action=timeline&channel=2PkyeIadiaLZXnMVYdJVh7w7"

Thanks for the quick response!

I would've sent a PR, but I don't have PHP set up on my local machine.
