Fixed group report false configuration parameter

[asteriscos]

Hi team,

this fixes a python exception when some PDF report options where not selected. Also fixes the documentation url to use current version instead of a fixed one.

Closes #1247 #1093

To test it:

• Go to Management / Groups
• Edit a group configuration with some example configuration like the following and save it:
  <agent_config name="agent_name"> <localfile> <location>/var/log/my.log</location> <log_format>syslog</log_format> </localfile> </agent_config> <agent_config os="Linux"> <localfile> <location>/var/log/linux.log</location> <log_format>syslog</log_format> </localfile> </agent_config> <agent_config profile="database"> <localfile> <location>/var/log/database.log</location> <log_format>syslog</log_format> </localfile> </agent_config>
• Select that group a generate different PDF report with different options selected
