Init Actions crash when given an empty state

[sleipnir]

Describe the bug

Methods marked as initialization end up popping an error when the actor's state is empty.

To Reproduce
Steps to reproduce the behavior:

1. Create init method on Actor
2. Start system
3. See error

Additional context
Apparently it is trying to deserialize a protobuf type with no bytes in the Any type.
