Repo LocalStore should not mix staged and committed metadata

The Repo struct is responsible for updating TUF metadata on
the local system. It implements a staging model, where multiple
metadata changes can be staged before comitting to the actual
repository. This is to support the ability to use keys on isolated
machines to sign the metadata.

Unfortunately the LocalStore implementation mixed together the
GetMeta method to return both committed and staged metadata,
which resulted in tests getting confused about treating staged
metadata as being committed, without actually committing the
metadata. This patch changes this behavior in order to have
separate APIs to read staged metadata when it is actually needed.
