./scripts/tests.sh fails: the argument for option '--vm' [hera] is invalid

[meowsbits]

I ran the script ./scripts/tests.sh with the build argument, and get error: the argument for option '--vm' is invalid.

Seems like an issue with aleth version? Or hera value needs to be the path/to/hera.so?

> ./scripts/test.sh build
