* fix(community): stop re-joining comm when receiving a sync community msg
Fixes an issue with chats being reset. Since joining a community resaves the chats with the synced default value, it resets the sate of the chats, losing the unread messages, the muted state and more.
The solution is to block the re-joining of the community. In the case of the sync, we catch that error and just continue on.
* fix(import): fix HandleImport not saving the chat
Doesn't change much, but it could have caused issues in the future, so since we might have modified the chat, we make sure to save them
Also adds a test
* fix tests
This adds checks to `HandleCommunityRequestToJoin` and
`AcceptRequestToJoinCommunity` that ensure a given user's revealed
wallet addresses own the token funds required by a community.
When community has token permissions of type `BECOME_MEMBER`, the
following happens when the owner receives a request:
1. Upon verifying provided wallet addresses by the requester, the owner
node accumulates all token funds related to the given wallets that
match the token criteria in the configured permissions
2. If the requester does not meet the necessary requirements, the
request to join will be declined. If the requester does have the
funds, he'll either be automatically accepted to the community, or
enters the next stage where an owner needs to manually accept the
request.
3. The the community does not automatically accept users, then the funds
check will happen again, when the owner tries to manually accept the
request. If the necessary funds do not exist at this stage, the
request will be declined
4. Upon accepting, whether automatically or manually, the owner adds the
requester's wallet addresses to the `CommunityDescription`, such that
they can be retrieved later when doing periodic checks or when
permissions have changed.
