Smack 4.2.1-beta2-SNAPSHOT OmemoManager#regnerate does not update server DeviceList

The test arecarried out with the following two devices. aTalk client has reflection implementation as mentioned in

Devices under test:

a. N3 - leopard@atalk.org(Note3-aTalk)

b. S3 - swan@atalk.org(S3-aTalk)

Initially N3 and S3 are setup to communicate in Omemo mode and olmMessages sending between them are working as expected.

Then performed an omemoDevice regeneration on S3. Check S3 sqlite database, and confirm all tables are correctly updated with the appropriate data for the new deviceID. S3 also publishes its new bundle data onto the xmpp server. However it was found that the server DeviceList is left untouched and still contains the old deviceID’s.

When an olmMessage is sent from S3, its sid reflected the new generated deviceID. N3 detects the new deviceID is not in its database, and sends RatchetUpdateMessage.

The S3 new bundle preKeys are then fetched from server and updated to its N3 tables. N3 then re-established new session with S3 new the deviceID.

Therefore N3 and S3 omemo session cannot proceed further. S3 must restarts in order to get subscribeToDeviceLists() to update the DeviceList on the server.

Note: atalk must implement as per below link to get subscribeToDeviceLists() to work properly.
