Bug: sqlite3 does not depend on nltk and regex

In 0.21.1 deployment, when running import sqlite3 in the REPL it would load nltk and regex which is wrong.

It looks like for sqlite3 depends and imports fields are switched, between the repodata.json and the meta.yaml

but then other packages seem to be fine.

This is serious enough to probably warrant a 0.21.2 release, as it adds an extra MB for apps that load sqlite3.

Version which reproduces: 0.20.0, 0.21.1 (and probably those in between) Version which don’t reproduce: dev

Also mkpkg should substitute - for _ in the imports field since this often is enough to give a correct result.

We should add a new key top-level in meta.yaml or something similar and should not use test/imports for calculating the top level import name. It’s so easy to make a mistake…
