Opening a URI like `bitcoin:bcrt1qu7nl0nxfqwhrrf6v0t60asvq3dympgqdhg03rn?amount=0.00010000` from Chrome on macOS still works as it should.

But opening it through the console, e.g. `/Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt bitcoin:bcrt1qu7nl0nxfqwhrrf6v0t60asvq3dympgqdhg03rn?amount=0.00010000` leads to a duplicate entry on the send screen.

So on macOS it's annoying when debugging the send screen, but otherwise harmless. But we should test the URI handler on different platforms.
