Queries in new objects are not evaluated correctly
When new object is created, all queries that are included (i.e. `collection.data`, `collection.samples`,...) are constructed in a wrong way, because object's id is not yet known and filters are applied with `id=None`.

Queries shouldn't be initialized in `__init__`, but on the first call and error should be raised if `id` is not yet known.
