ethereum: fix tests after forge 1.0 release

Forge 1.0 changed the meaning of expectRevert, by no longer considering
internal calls by default:
https://book.getfoundry.sh/guides/v1.0-migration#expect-revert-cheatcode-disabled-on-internal-calls-by-default

We work around this by overriding the default config in places that rely
on this expectation, and simply by invoking external calls in places
that just incidentally relied on this.
