[BUG] Typo in def of enocde_conversations_to_json

[rizlas]

Hi,
i was using helpers.py yesterday and i found a typo in enocde_conversation_to_json function definition

If it wasn't wanted I would suggest to change it:

From:
def enocde_conversations_to_json(conversations)

To:
def encode_conversations_to_json(conversations)
