In Charity pallet, the pot is not initialized with an account minimum balance.

Initially raised in #308. This can be verified with using polkadot-js app to query the system:account of the charity account.

Verified at the following screenshots.

1. To get the charity pot account.

2. Purge the chain, and check the pot account balance.

@JoshOrndorff On this branch, I have written test to include pot initial minimum_balance into consideration. Test passes now. The main changes is in fn new_test_ext(), there is also these lines:

crate::GenesisConfig {}
        .assimilate_storage::<TestRuntime>(&mut t)
        .unwrap();

being run. With this, it means min balance is indeed set properly in pot account.

But when running regularly, interacting using polkadot-JS app, if we query the pot account after purging a chain, we still see the pot amount start from 0 instead of the min balance.

Not sure where the bug is...

Good debugging work @jimmychu0807 This is a mystery to me as well.
