@tiensonqin Tested all the fixes and they work great! 🐛 ⚡ I'm not sure if removing deleted pages from Recents is improved ux. It may confuse users if they rely on Recents as unmodified history

@logseq-cldwalker Maybe we can leave the deleted pages in Recents and show a message like "This page has been deleted, do you want to create a new one or remove it from Recents?". I'm going to merge this PR, we can improve this later with more feedback.

The nice idea of Recents was like it were before New Search: Recents is a search terms. And selecting the search term leads to input it to query filed, not to opening a page.
This idea has advantages:

1. There is no problem with deleted pages
2. It solves the case when I make a mistake in prev search and want to change only one character, not the whole page name (which can be very long)
3. This partially solves the requests like this one, without a special shortcut (but TAB-like shortcut (or right arrow) still a very nice idea for very long page names with complex hierarchy)
