[commit] master: remove pointless "lost track of ... messages" warnings

[Oswald B. <os...@us...>]

commit 254d2be9f47fd63285ac9c39d32be8bec7c7a6f7
Author: Oswald Buddenhagen <os...@us...>

    remove pointless "lost track of ... messages" warnings
    
    it doesn't really add any value when resuming after an interruption, as
    incomplete propagations are perfectly expected, and are recovered from.
    but it does make sense in the non-UIDPLUS path, where not finding just
    stored messages indicates a problem.
    so move the reporting from match_tuids() to msgs_found_new(), and remove
    a redundant warning from the latter.
    
    amends 6577bf3e.
