cli/command: internalize constructing ManifestStore

The CLI.ManifestStore method is a shallow wrapper around manifeststore.NewStore
and has no dependency on the CLI itself. However, due to its signature resulted
in various dependencies becoming a dependency of the "command" package.
Consequence of this was that cli-plugins, which need the cli/command package,
would also get those dependencies.

- This patch inlines the code to produce the store, skipping the wrapper.
- Define a local interface for some tests where a dummy store was used.
