ISSUE:       6166
TITLE:       Enhance dynamic libraries loading related error messages
DESCRIPTION:
  We intentionally try to load unit from non-existent UDR module with name "udrcpp_foo".
  Message 'module not found' issued BEFORE fix - without any detailization.
  Current output should contain phrase: 'UDR module not loaded'.
  Filtering is used for prevent output of localized message about missed UDR library.
JIRA:        CORE-5908
FBTEST:      bugs.core_5908
