Removing hash as it is different between tests despite the image being the same.

Initially when I added this hash into the tests it was consistent on the same machine I was running the tests on, but after try it on a different machine I see it produces a different hash. The images still look the same, so there is likely some tiny variations for whatever reason. Removing the hash for now so the tests still pass.

Yeah, this is an issue across OS's too, our good friend floating point ruining things for everyone
