Fastly crate panicking when a dictionary item doesnt exist

[muda-fastly]

While doing some testing today locally, i came across a panic on the fastly crate. This seems to be happening because the dictionary item lookup fails because the item does not exist in the dictionary:
Aug 27 16:50:20.450 ERROR request{id=0}: Hostcall yielded an error: Unknown dictionary item: Manifest-2d98131 thread 'main' panicked at 'fastly_dictionary::get returned an unrecognized result', /Users/mmohammed/.cargo/registry/src/github.com-1ecc6299db9ec823/fastly-0.7.3/src/dictionary/handle.rs:81:23

I do not see this error on C@E.
