Fix and simplify openUrlInBrowser

The code was not previously working in case no default browser is set[1] AND NewPipe is set as default handler for the link in question. We improve it by telling the system to choose the target app as if the URI was `http://`, which works even if the user has not set a default browser. [1]: also the case if platform refuses to tell an app what the user's default browser is, which I observed on CalyxOS.
