More consistent and informative graph name

This is about two related issues:

  • The graph name is taken to be the folder name. It’s pretty inconvenient for typical directory structures like: project/notes, project/logseq, etc, since the name would be notes, logseq, etc. for every project.

  • The switch-to-graph menu shows the parent folder also, like in project/notes, project/logseq. I guess this is done in order to address the previous problem. But then it’s inconsistent with the name actually shown after graph switching.

I propose to simply be consistent and also show the parent folder as part of the graph name, so more context is provided.
