ISSUE:       5691
TITLE:       Inconsistent output when retrieving the server log via Services API
DESCRIPTION:
  Test gets FB home directory and copies firebird.log to *.tmp.
  Then it makes firebird.log empty and retrieves it via services API. Output should be empty.
  Finally, it opens firebird.log and adds to it several empty newlines.
  Repeat retrieveing content - it also should not contain any characters except newline.
NOTES:
[7.12.2021] pcisar
  Test requires direct changes to firebird.log which could require elevated privileges!
JIRA:        CORE-5418
