    [BROWSEUI] CAutoComplete::OnAutoCompStart(): Wait on the thread only when there is a
handle.
    
    Avoids spamming
    (ntoskrnl\ob\obwait.c:441) Failed to reference the handle with status 0xc0000008
    
    CAutoComplete::FinishCompletion(): Remove two useless 'if (m_pThread ||
!m_hThread)'
    tests: No need to check these after each code instruction...
