I could have sworn the context property was required, but evidently it
isn't and we weren't handling the case when it was missing.
This PR updates things to set a default location of the current
directory if the context is absent. Some unit tests are also added.
Fixes#78.
Part of https://github.com/pulumi/ci-mgmt/issues/915

- Lock the version of the CLI and therefore codegen for consistent build
results.
- Ensure the local language plugins are using by disabling ambient
plugins.
Enable respect schema version
Remove setting version at SDK build time
