unify ethereum revert/throw/etc error expectations

[shrugs]

🎉 Description

We have a bunch of different error handlers for solidity-specific things. They should just be one assertion function that accepts a configuration options hash if and only if the caller needs to be more specific than just "it fails".

Maybe something like:

await expectFailure(
   myPromise,
   { onlyRevert: true }
)

We need to

• write this assertion

• update literally everywhere in the codebase that uses the other styles

• 📈 This is a feature request.

Bonus points for making it compatible with "should"-style assertions.

See #938, #917 for recent issues to keep in mind.

Also the current assertRevert doesn't work when the revert happens during the contract deployment.
Example: await assertRevert(Contract.new(args));
