e2e chats allow non-encrypted chats to be sent

[dswebbthg]

Description:

Encrypted channels allow users to send non-encrypted text

Steps to reproduce:

1. create an encrypted channel with only yourself as the user
2. send message via app that supports e2e, result = encrypted message
3. login via android app (which seemingly doesn't support e2e), send message in channel. message is sent unencrypted and can be seen on the thick client

Expected behavior:

disallow sending of non-encrypted messages on encrypted channels

Actual behavior:

allows sending of non-encrypted messages

Additional context

Relevant logs:

[reetp]

Android app does not currently support encryption. It is on the roadmap:

RocketChat/Rocket.Chat.Android#566

However, I am not sure you should be able to send a plain message in an encrypted channel.

In my opinion encrypted chats shouldn't allow any non-encrypted messages, but it definitely does right now.
