  Changed paths:
    M src/lib-index/mail-transaction-log.c

  Log Message:
  -----------
  lib-index: mail_transaction_log_find_file() - remove wrong optimization.

When opening the index, it's possible that:

process A: .log is opened with seq=1
process B: Rotates the .log and writes a new dovecot.index with
  log_file_seq=2
process A: dovecot.index is opened. mail_transaction_log_view_set() now
  wants to file log_file_seq=2 with mail_transaction_log_find_file(), but
  because open_count==0, the .log isn't refreshed.
