Screenshot 'on exception' doesn't work on nemo@^4

[ruslK]

with config for nemo@4:

"screenshot": {
            "module": "nemo-screenshot",
            "register": true,
            "arguments": [
                "path:report/screenshots", [ "exception"]] }

there is no screenshot on exception. But screenshot working on click, or nemo.snap().

[grawk]

nemo.snap() uses internal screenshot code, as opposed to using the nemo-screenshot module. The nemo-screenshot module used ControlFlow/PromiseManager based code to capture screenshots on exception. That method no longer works now that the PromiseManager is deprecated. So this is essentially an enhancement request. Marking as such, as well as "help wanted" for now.
