tests should not generate console errors

When I run Alchemy tests in "rewards.ts", not headless, so I can see the browser, I see in the browser console the errors below.


The line that must be generating the console error is in arc.js, arc.ts:

```
if (abiName === 'GEN') {
abiName = 'DAOToken'
}
let artefact = abis[version][abiName || '']
if (artefact.rootVersion) {
artefact = abis[artefact.rootVersion][abiName || '']
}
```

Start with the Alchemy tests in rewards.ts and run them non-headless so the browser console is visible. Inspect the arc.js and arc.ts lines shown in the issue alongside the reported console errors; done means the tests no longer generate those browser console errors.
