Unable to create multiple pages with same name but different type

### What Happened?

The [documentation](https://github.com/logseq/docs/blob/master/db-version.md) sais:

> Page names are unique by tag e.g. there can be Apple #Company and Apple #Fruit.

This does not work anymore. It creates an empty block on the first page instead!

### Reproduce the Bug

1. Create page "Apple #Company"
2. Then try to create page "Apple #Fruit"

### Expected Behavior

A second page is created.

### Additional Context

This is an important feature. Please prioritize fixing it.

I tried to import both pages from EDN, but i ended up with one page with both tags.

Demo: https://youtu.be/2jwlVf3FZtI?si=XkPi_Lh0r9zbAEQC&t=49

```
{:pages-and-blocks
[{:page
{:build/tags #{:user.class/Firma-HacVBUZC}, :block/title "Apfel"},
:blocks [{:block/title ""} {:block/title ""}]}],
:classes {:user.class/Firma-HacVBUZC {:block/title "Firma"}},
:logseq.db.sqlite.export/export-type :page}
```

```
{:pages-and-blocks
[{:page
{:build/tags #{:user.class/Frucht-GhI7U-kc}, :block/title "Apfel"},
:blocks [{:block/title ""} {:block/title ""}]}],
:classes {:user.class/Frucht-GhI7U-kc {:block/title "Frucht"}},
:logseq.db.sqlite.export/export-type :page}
```

(i'm using german names here because i messed up the english page)

#### Workaround

Have one page with tag 1
have the second page with a differen name and tag 2
the rename the second page to the same name of first. that works, because they have different tags. so the database accepts it, but the UI don't let me create the second page

### Are you willing to submit a PR? If you know how to fix the bug.

- [ ] I'm willing to submit a PR (Thank you!)

Read db-version.md and reproduce the two page-creation steps on the listed Logseq build. Compare the UI result with the EDN import examples and the rename workaround; done means creating Apple #Company and Apple #Fruit produces two distinct pages without an empty block on the first.
