ISSUE:       6477
TITLE:       Wrong dependencies of stored function on view after backup and restore
DESCRIPTION:
  We make backup of this test DB and restore it to other name using PIPE mechanism
  in order to skip creation of unneeded .fbk file
  See: https://docs.python.org/2/library/subprocess.html#replacing-shell-pipeline
JIRA:        CORE-6233
FBTEST:      bugs.core_6233
