Fix color sampler in wrap around mode
Some paint devices don't support painting in wrap around mode, but they can still be sampled from, so bypass the supportsWraproundMode check when color sampling.
There's a similar workaround in KisFillPainter::fillRectNoCompose, but this still seems like a bit of a hack. I'm not sure if there's a better way to fix the underlying cause, whatever that is.
Test Plan
Enable Wrap Around Mode, try to color sample from the 'copies' of the image with sampling set to "All Visible Layers", or on a File Layer.
