Actually this was already the case for certain commands, but some of them was left unguarded for such cases. This commit also fixes #109. The behaviour of silently skipping key prefixing when a command has no arguments may change in the future so we added explicit tests as guards for future changes. Predis\Command\Processor\KeyPrefixProcessor will continue to skip key prefixing on empty arguments, regardless.
