room/encrypted: Fix the OlmV1 deserialization

Browse Source 
A m.room.encrypted event with the algorithm type
"m.olm.v1.curve25519-aes-sha2" will have multiple ciphertext values.

The documentation for the struct field even mentions that the
ciphertext is a map, yet it only expected one body and one message type.

This patch fixes the de-serialization and puts all the available
ciphertext values into a hashmap.
