Stop image picker thumbnail flicker

The May 17 picker performance change made activated thumbnail loads asynchronous, which undid the earlier anti-flicker fix and let carousel movement flash blank thumbnails. Keep lazy activation, but load activated thumbnails synchronously so theme/background picker navigation remains stable. Add regression coverage for the thumbnail loading mode.
