add testID prop

[swizes]

With the changes now the QR SVG component accepts testID prop, so we can assert the visibility of the QR Code in unit/e2e tests.

Example usage:

    <QRCode
      value="Just some string value"
      logo={logoFromFile}
      testID={'SomeTestID'}
    />

@awesomejerry Any chance to merge this?

I see you added testID, but you didn't pass it to the Svg component.
So basically this code won't work
