App breaks when changing action type in unknown transaction

[arrenv]

NOTE: This needs more info and design updates, tracking it for now.

Steps to reproduce

1. Perform an arbitrary transaction in a Colony.
2. This can be done by calling the makeArbitraryTransaction colony contract method directly.

You can see this in product in the Betacolony or by accessing this transaction directly - https://app.colony.io/beta?tx=0x5817c758c51c9200201ae4c4fa72fc11de19793cdbf018327b22b2e7a0661544

Expected behaviour

• Opening an unknown transaction in the action panel and changing the "Choose action type" should not break the app.

Actual behaviour

• Opening an unknown transaction in the action panel and changing the "Choose action type" breaks the app.

This title is kinda misleading :)

This issue doesn't need to "fix" the changing title interaction, but rather to deal with handling arbitrary transactions in the UI

Yeah, I figured that was more of a feature that needs designs, contract updates, etc. I just wanted to make sure the app didn't break when opening up one of these transactions in the meantime.
