Light preset not stored correctly when swiching RGB(W)<->CCT

[martinbosma]

When on e.g. RGBW mode and you pick a color, then switch to CCT mode but don't change the color and click an empty preset, the preset will contain the color from the previous mode. It seems to works both ways, but it could be because when going CCT -> RGBW the saturation close to 0.

Selecting green in RGBW mode:

Switch to CCT and click an empty preset:

Selecting white in CCT mode:

Switch to RGBW and click an empty preset:

While fixing this I found another bug: for the CCT wheel, if you drag along the bottom half, it snaps back to the top half of the wheel after release. I've also fixed this as part of the same PR #2651

Although the issue has improved with e259f40 , it seems to store a red color when switching from RGBW to CCT.

I will check this with the updated beta image - I think the colour might be reset in the backend, and then gui-v2 needs to take this into account.

I've made related fixes in #2664, which may also resolve this issue.
