feat: migrate state to new database name (#4938)

Browse Source 
* Merge setup and navigate functions

Whenever we navigate we probably want to make sure the editor is ready
so might as well just have one function.

* Add customizable entry and workspace directory

* Add test for state db migration

* Update Code

This contains the state migrations.
