Test long running received record processing after task is complete

[ekigamba]

Check if the processing of received records is affected if it takes longer than after the sync complete command is sent by the sending device and received by the receiving device.

Or does the async task die?

It also seems that the Async task dies if the connection breaks while it is not done processing, sometimes on the sample app, the last record id is logged but it is not saved in the DB. Other times it is logged but not saved in the DB.
