I have encountered a crash in the app after syncing, looks like a
community has been created without a Config.
This crashes the app after the user logs in.
This commit prevents the app from crashing, but does not fix the
underlaying issue (that's something I will have to investigate).
Added tests to validate the behavior.
Check community exists
Similar to `CheckPermissionToJoin()` we now get
a `CheckChannelPermissions()` API.
It will rely on the same `PermissionResponse` types, but gives
information about both `ViewOnlyPermissions` and
`ViewAndPostPermissions`.
This is needed so that when they are bundled into archives, receiving
nodes can still verify the messages payload using its signature.
This commit introduces a new `waku_messages` table and APIs to store
such messages. Waku message payload is store for any message that has
a topic that matches any of the admin communities chats.
Closes#2566
