🎨 make sqlite filename absolute (#7585)

no issue

- add tests for makePathsAbsolute
- add support for windows paths

When Ghost-CLI inits the database of the current GhostVersion (in /current), then it uses knex-migrator to do that.
Knex migrator is reading the .knex-migrator file of the current Ghost version. This returns a relative path to the database location.
The problem: knex-migrator will init the database in the root folder of Ghost-CLI /content/data instead of /current/content . And when you start Ghost (ghost start), it always complains that
that database is not initialised, because it expects the database in /current/content...

* 🎨  move config_spec to config/index_spec
- add one more test case
