fix(web): multi-select

[wuzihao051119]

Fix wrong behavior in using shift key to select multi-asset.
Correct:

correct.mp4

Wrong:

wrong.mp4

Selecting asset in range (beginBucket, endBucket) and Selecting dateGroup in range [beginBucket, endBucket] is correct logic.

I can't reproduce this issue

[wuzihao051119]

The key point to reproduce this is:

1. selecting the non-first photo in the bucket when selecting the start photo (pay attention to the selection icon in the thumbnail)
2. selecting the photo in the non-first dateGroup in the bucket when selecting the end photo (pay attention to the selection icon in the dateGroup).
