Exception when getting history from cli

(ngcccbase)$ ./ngccc-cli.py --testnet history dardasim

Traceback (most recent call last):

AttributeError: ChromaBlockchainState instance has no attribute 'get_block_height'

If I set height to -1 in wallet_model.py +130 everything works fine, but I doubt it's a healthy workaround.

I don't know if this helps in any way, but after copying an old testnet.wallet into a new clone I got the following when running the same command:

    history = self.controller.get_history(asset)

    height = self.ccc.blockchain_state.get_block_height(
AttributeError: 'ChromaBlockchainState' object has no attribute 'get_block_height'

So it's still complaining over get_block_height, but it also provides the expected output. But this only works once. Afterwards I only get the error.
