Only black or white path color if "cancel accent color" is selected

[lightproof]

As of Logseq 0.10.7, if cancel accent color option is selected, which is required for some themes, the bullet path color is then becomes strictly black for light theme, or white for dark theme. Bullet path color override setting in this case is also ignored.

It was probably something on Logseq's side, because in Logseq 0.10.8 bullet threading seems to work properly.
