Testing for ccd006-citycoin-mining

[whoabuddy]

Since this contract is very similar to the original, there's already work in #59 to duplicate the test structure. The biggest difference is it will require passing ccip-014 so a separate function could be built similar to passProposal that will:

• deploy the dao
• mine and stack for 3 cycles
• confirm claims before ccip-014
• execute ccip-014

Then a similar function may be used, or a least a pattern where:

• mine and stack for 3 cycles
• confirm claims after ccip-014

Note: this was easier to approach from the context of ccip-014 tests, which now verify:

• mining succeeds in v1 before the upgrade
• mining fails in v1 after the upgrade
• mining succeeds in v2 after the upgrade
• claims from v1 succeed after the upgrade
• claims from v2 succeed after the upgrade
