Invalid contract address in tests

Hello,

I am trying to run the tests with `make test` and I have an error with the DOMAIN_SEPARATOR being invalid.
I tracked down the issue: The addresses in `bin/conf/hevm.sh` are not the same when I run the tests on my machine. I replaced the addresses for chai, vat, pot, join and dai with my own generated addresses and most of the tests works (the tests with the hardcoded signature still fail, I would have to update them too).

Am I missing something to generate the same addresses as in `bin/conf/hevm.sh`?
