Can't create DAO with single coin [Bug]

[danieljperry]

What happened?

When creating a DAO, the wallet must hold two coins: One to create the DAO, and one to mint the DAO CATs. This is an issue because I would expect most new DAOs to be created from a new wallet, which would receive a single coin from another wallet.

For example, the following command to create a DAO:

chia dao create --proposal-timelock 10 --soft-close 2 --attendance-required 1000 --pass-percentage 5000 --self-destruct 10 --oracle-delay 5 --proposal-minimum 0.000001 --filter-amount 1 --cat-amount 100000 -m 0.00001 --fee-for-cat 0.00001

Will fail with this error if only one coin is present:

Exception from 'wallet' {'error': 'Transaction for 100000 is greater than spendable balance of 0. There may be other transactions pending or our minimum coin amount is too high.', 'success': False}

I will document this on our website, but it would be better if either:

1. The error message could be more specific that another coin is required, or
2. (better) The DAO could automatically (or maybe prompt to) split the coin prior to creating the DAO, or
3. Create the DAO first, wait for change, and then create the DAO CATs

Testing on main, this does give a more meaningful error:
ValueError: DAO creation requires at least 2 xch coins in your wallet.
Ideally in a future version, if there is only one coin, it would automatically be split into two.
