Unable to find repository error

[HiromuHota]

This is a regression of 4dcb443.

How to reproduce

1. Create $CATALINA_HOME/system/kettle/slave-server-config.xml with the following content:

<slave_config>
  <max_log_lines>10000</max_log_lines>
  <max_log_timeout_minutes>2880</max_log_timeout_minutes>
  <object_timeout_minutes>240</object_timeout_minutes>
  <repository>
  <name>repo8.0</name>
  <username>admin</username>
    <password>password</password>
  </repository>
</slave_config> 

2. Enable user authentication and log-in (e.g., user=chrome), but chrome/repositories.xml does not define a repository called repo8.0.

The following error is recorded in catalina.out.
