fix: dynamic import must not handle __esModule flagged modules

[petermuessig]

Standard NPM packages like jsPDF are also detected as static objects but compared to UI5 static objects they must not be returned as default.

NPM static objects:

(await import("jsPDF")); // { __esModule: true, jsPDF: /* jsPDF class */, ... }
(await import("sap/m/MessageBox")).jsPDF // jsPDF

UI5 static object:

(await import("sap/m/MessageBox")) // { __esModule: true, default: /* sap/m/MessageBox */... }
(await import("sap/m/MessageBox")).default // sap/m/MessageBox
(await import("sap/m/MessageBox")).default.alert // sap/m/MessageBox#alert
