    Check on schemes not stores

    Since the `_upload` method loads the store based on the scheme, we need
    to check whether the scheme exists in the known schemes instead of
    checking in the list of known stores. Without this fix, stores with a
    scheme name different than the store itself will not be usable through
    the `x-image-meta-store` header.
