fix(core): Fix data decryption on credentials import (#7560)

Due to a change, during the credentials import command, the core's
Credential object is being called through its prototype. This caused the
Credential's cipher variable to not be set, thus no cipher service being
available during import. This fix catches this edge case and provides a
fix.
