Update smoke-test.yml

Fixes #101.

I already did this for the unit tests but didn't fix the smoke tests. Essentially we need to make sure that the workflow runs pip install -e .[dev] with the -e so that the repo's directory structure is maintained. If we don't include the -e then the unit tests can't find the testing database.
