fix: component highlight fall backs failing 

Color/theme created with `highlight_group_name` are handled with link.
Because of that we don't have a table on bg/fg instead a name .
Currently component highlights doesn't take this into account.

After colors from those groups will be extracted to provide fall backs
for component highlight.
