Set collection_id on search for pgstac get_item; update to pgstac 0.3…

….4 (#270)

* Update to pgstac 0.3.4

* Include collection_id in get_item search.

I've seen strange behavior described in
stac-utils/pgstac#58, where searching only
by an Item ID was returning the incorrect Item. Specifyng the
Collection ID, which this method should be doing, solved this in my case.

* Fix NotFoundError message

* Update CHANGELOG
