Messed up broker configuration file without failover configuration

[scitechff]

Hello,

OS: CentOS 7.4
centreon-broker: 3.0.13
centreon-engine 1.8.1
centreon-web: 2.8.19

follwing the discussion in issue #126 I removed all failover configurations for my broker. Without the failover configuration, the broker config file for the rrd file generator is not generated correctly anymore.

Steps to reproduce the issue:
For my central server I configured two broker accordingly to the best practices. One for the sql, perfdata and rrd forward output. And a second one for the rrd file generation. For both broker I removed all failover configurations. For the first broker the config file is generated correctly. For the second not.

Config file for the rrd broker with failover:

Config file for the rrd broker without failover:

Describe the results you expected: Correctly generated config files.
