Tests

This cannot really be tested right now since the default push rules on server side have not been deployed yet (need to validate some MSC first). The only notification we can have now is when starting a poll in an encrypted room.
On my side, I have tested it by adding the corresponding push rules on my test account.

In encrypted room:

• Start a poll
• Check you receive a notification on another device
• Start a live location share
• Check you don't receive any notification (note the unread notification counter is not correct due to the lack of push rules)

In non-encrypted room:

• Start a poll
• Check you don't receive any notification (note the unread notification counter is at 0 due to the lack of push rules)
• Start a live location share
• Check you don't receive any notification (note the unread notification counter is at 0 due to the lack of push rules)

Tested devices
