AE: Array method in AE freezes lively

```javascript

import _ from 'src/external/lodash/lodash.js';
const options = [1, 2, 3];

aexpr(() => {
let x = 0;
options.forEach(y => x+=y);
lively.notify("x: " + x);
return x;
}).onChange(lively.notify);

options[0]++;
options.values()
```

Creating the hook triggers the AE Evaluation, which creates a hook and so on

Start by running the JavaScript reproduction in the issue and tracing the AE evaluation and hook-creation path it describes. The fix is complete when creating the expression does not recursively create evaluations or freeze lively, while the array example can still update and notify.
