Support multi-hash in multi-trie via PlainDB (paritytech#1106)

* Temporarily pin trie to #2 * Use generic and delay trait object casting Rust does not support super-trait upcasting * Add PlainDB impl for Ephemeral * Add PlainDB trait alias for completeness * Use PlainDB for test TrieBackendStorage fetch We always check overlay first for a storage fetch, which already checked null data. Using PlainDB here makes it work nicer with other PlainDB overlays. * Update trie reference * Use HashDBRef in places when approriate * Use PlainDBRef in places when approriate * Update trie crate reference * Remove unused HashDB::keys * Patch dependencies * Fix cargolock * Update cargo lock again
