* Upgrade Mjolnir from 1.1.20 to version 1.2.1

https://hub.docker.com/r/matrixdotorg/mjolnir/tags

using the "latest" tag seems inefficient as it doesn't actually redirect to the latest release

In any case, the latest release is now 1.2.1

docker pull matrixdotorg/mjolnir:v1.2.1

Add support for creation of Jitsi internal authentication users in vars.yml

The check was checking for an empty string in `matrix_jitsi_prosody_auth_internal_accounts`,
which is unlikely to happen. We should check for an empty list instead.

The check was not validating username/password values, so telling the user that they need a non-empty
username/password is misleading. It was merely checking if there's at least one entry in the list.

This patch adjusts the check and message accordingly.

This is useful when Synapse is using a worker setup. In that case,
we don't want appservices to connect to `matrix-synapse:8008`, because
not all APIs are exposed there.

Seems like there's such a variable in the
`matrix-bridge-appservice-slack` role, which is probably where it got
copied over from.
