Fixes #2862

Description
The as_hal family of functions will invoke the callback with None if the wrong api is used as the generic type. This is because the HalApi generic performs lookup in a different hub. However the get function in the storage will fail if the id used for lookup is not in the storage (because you specified the wrong generic type) and therefore panic.

To solve this, a try_get function is used for all as_hal functions to ensure that as_hal will actually return None instead of panicking.

LGTM, will need to make sure this behavior sticks with the new hubs
