fix(electron): clone db file when enable cloud for desktop (#5028)

At the moment on desktop the user's local blob data will be lost after enable cloud.
This is because blob data is only synced from old idb to new idb, but not sync into sqlitedb.

This pr will simply clone the db file for desktop app. It should also speed up the time when enabling cloud for a large local workspace.
