Highlights should be (re)defined on colorscheme changes

[blueyed]

This affects at least the vcsdiff highlights here: https://github.com/tomtom/quickfixsigns_vim/blob/bda44072bd866cc9efb81092467dfdf976358050/autoload/quickfixsigns/vcsdiff.vim#L125-L127

After changing the colorscheme those get cleared (for me at least).

This can be done on ColorScheme.

Would you like a PR with that?

Could not find other places - other highlights are linked? (but I only quickly grepped).
