t8n pre state that has precompiles

[winsvega]

we should define the t8n behaviour if pre state contains code for address that is precompile. as it might create issues such as here:

@marioevz I think this has already been handled?

[winsvega]

the address collision is handled by state class pre.deploy_eof() dynamic contract address generation. so it should not be the problem now. unless we explicitly generate a test with a pre that has precompiles overwrite.
