Fix quick bar dark mode contrast, filter returning all items, no primary text

[donkawechico]

Proposed change

Fixes a few regressions caused by #7359:

1. List item selection highlight not high enough contrast
2. Sequence filter returning all other items after the highest-scored item

...and an unrelated but minor bug discovered after beta release:
3. List item primary text showing nothing when friendly name is empty string

There's still a bug with topmost item selection not showing hover color when input field has focus.

The first item should have hover color on because it's selectable by hitting enter. I wasn't able to find a fix using the this_setFocusFirstListItem() method.

The contrast being too low in dark mode is not a quick bar only issue, but for every mwc-list so we should fix it for all.
