result of async controller functions are not transported correctly from browser- to Node.js-scope

[vobu]

Describe the bug
Async functions in a UI5 controller (browser-scope) don't resolve correctly in Node.js-scope: instead of the atomic result, a wdi5 Object with (partly) a Promise signature is returned.

To Reproduce
Steps to reproduce the behavior:

Test in question: examples/ui5-ts-app/test/e2e/Basic.test.ts

$> cd examples/ui5-ts-app
$> npm run authentication:basic-auth -- --spec Basic

# (...)
[0-0] Error in "Basic.should resolve an async Controller function"
Error: expect(received).toEqual(expected) // deep equality

Expected: 10
Received: {"_aProtoFunctions": ["then", "catch", "finally", "hasOwnProperty", "isPrototypeOf", "propertyIsEnumerable", "toString", "valueOf", "toLocaleString"], "_baseObject": {}, "_uuid": "f60ae34b-7c1c-4df0-ab04-09b4c0e06370", "catch": [Function bound _excuteObjectMethod], "finally": [Function bound _excuteObjectMethod], "hasOwnProperty": [Function bound _excuteObjectMethod], "isPrototypeOf": [Function bound _excuteObjectMethod], "propertyIsEnumerable": [Function bound _excuteObjectMethod], "then": [Function bound _excuteObjectMethod], "toLocaleString": [Function bound _excuteObjectMethod], "toString": [Function bound _excuteObjectMethod], "valueOf": [Function bound _excuteObjectMethod]}

Expected behavior
10 should be returned
