Resgrid.Console.exe dbupate throws unhandled exception

See original GitHub issue

Resgrid.Console.exe dbupate throws unhandled exception:

Unhandled exception. System.Configuration.ConfigurationErrorsException: The entry 'ResgridContext' has already been added.

I believe codes in line #86 and #87 can be removed as “ResgridContext” already exists after line #71 loaded AppOptions:ConfigPath successufully.

bool configResult = ConfigProcessor.LoadAndProcessConfig(Configuration["AppOptions:ConfigPath"]);

Or check the connection key before adding it to settings collection as below.

if (!configResult)
   settings.Add(new System.Configuration.ConnectionStringSettings("ResgridContext", Configuration["ConnectionStrings:ResgridContext"]));
else
{
   if (settings["ResgridContext"] == null)
   {
	settings.Add(new ConnectionStringSettings("ResgridContext", DataConfig.ConnectionString));
   }
}

Please correct me if I misunderstood something.
