fixes #216

lgtm, can you add this to the CHANGELOG?

This is also capturing logs, so we need to configure the dir for kv/sqlite but not for logs.

Logging component stdio to "/.spin/logs/"
Storing default SQLite data to "/.spin/sqlite_db.db".

@Mossaka i am not sure what i would add to the CHANGLOG for this as this is a fix to ensure that we do not have a change in this release with regards to the state dir
