[kronosapiens]

Closes #1228

Main

• Update to Hardhat 2.22 and cancun hardfork
• Remove calls to selfdestruct and update uninstall behavior for extensions
• Make better use of ColonyExtension.sol base class and remove boilerplate from extension contracts

Misc

• Miscellaneous improvements to coverage
• Split up reputation-test-non-gnosis Circle job to reduce total build times
• Make arguments to getMetatransactionNonce consistent among affected contracts

[area]

Make arguments to getMetatransactionNonce consistent among contracts

If this is the goal, then I believe you have missed:

• ColonyNetworkAuction
• IBasicMetaTransaction
• CoinMachine
• FundingQueue
• TokenSupplier
• Whitelist
• VotingReputationStorage
• VotingReputationMisaligned
• TokenLocking

Did you not touch incrementMetatransactionNonce because it's internal, or some other reason?

Fun to see a refactor that reduces duplication to the extent the coverage thresholds fail so more tests have to be written, that's good to see 😄

Thinking about this more, I'm not sure if there's much benefit to including uninstall as part of the extension interface in general. We can still support uninstallExtension at the network-level, but the implementation should be changed to:

1. Remove all permissions from the extension in the colony
2. Delete the extension from the installations mapping

I say this because we already have a deprecate function which does all of the restricting that we would add to an uninstall function, which makes me think that an uninstall which locks all functions would be mostly redundant.

If anything, the uninstall function on the extension should perform checks to see if we are ready to uninstall the extension via the network. I'm thinking of streaming payments here, where uninstall would simply error if there were unclaimed funds.

UPDATE: after discussing with @area we will delete both resolver and colony on "uninstall".
