fix(core): Initialize command cache when a capability is added

[lars-berger]

This line of src/ipc/authority.rs panics when a command is run after a capability is added at runtime (via add_capability).

    let cache = self.command_cache.get(key).unwrap();
    ...

add_capability deletes its corresponding command_cache entry here, which then causes the above line to panic.
