Importing a plugin's `index.js` file from other plugins means that it's no
longer possible to remove that plugin by removing it from `src/converse.js`.
Instead, all plugins need to be imported in proper order from
`src/headless/headless.js` and `src/converse.js`.
Updates #3026
Add the ability to send OMEMO corrections.
Refactor how OMEMO messages are sent to avoid having to override
`sendMessage` and thereby also allowing corrections of OMEMO messages to
be sent out.
Add two new hooks.
- getOutgoingMessageAttributes
- createMessageStanza
Promises only get recreated upon logout, not reconnection.
However OMEMO was getting re-initialized on reconnection and
`_converse.omemo_store` was also deleted.
This caused a race condition where an incoming MAM message would cause
`parseEncryptedMessage` that then throws an AttributeError because
`_converse.omemo_store` is undefined because OMEMO isn't yet
initialized.
Waiting for the `OMEMOInitialized` promise doesn't help because it's
still the old (already resolved) promise from before the reconnection.
When calling `getDeviceList`, wait for the devices to be fetched
Otherwise a race condition might occur, whereby a new device gets
created in the collection, and then removed again as the collection is
replaced with the values fetched from the browser-storage cache.
Also created `converse-omemo-fingerprints` component to asynchronously
render fingerprints in the user details modal. Was done as part of this
commit because due to `getDeviceList` being async, the relevant test for
the modal were also failing
