Fix layout height for suggestion tile.

- set minHeight instead of using a fix height, so that when the
font/display size is set to larger, the height will expand accordingly
to fit all elements in the suggestion card.

- revert the change that tint all suggestion icons. The previous logic
should be used to determine if we should tint the icon or not.
