Revert "perf(web): optimize date groups"

[michelheusschen]

After #7593 got merged I noticed some issues:

• Updating assets after an upload fails (except upload into a new bucket)
• AssetStore.removeAssets no longer updates UI state (except deleting all assets in a bucket)
• From code it looks like assets and date groups are no longer being sorted and just depend on insertion order

Quite a few things have been overlooked and I think this PR should be reverted

We will also need to revert #7563

@mertalev are you still working on this to find the cause or you are OK reverting and return to this matter at a later time?

[mertalev]

I don't have the time to look into this more right now, so we can revert it and look at it later.

This part was intentional since the time bucket response already returns assets in sorted order. Re-sorting everything is a waste.
