Emergency shutdown on secondary servers after CREATE TEXT INDEX [CR #611990]

A secondary server goes into emergency shutdown, when:

• It is started with the -sf external_library_full_text flag, which disables loading of external libraries, and

• The user issues a CREATE TEXT INDEX statement on the coordinator with a text configuration that uses external libraries.

All other servers replay the DDL successfully.

To avoid the problem, start secondary nodes in the multiplex without the -sf external_library_full_text flag.
