The Xray Action message should only be logged when there is Xray Tasks in the current job

In order to support remote agents, before building the job, an Xray pre-queue action takes place to scan if the current job has any Xray task. If there is, then it will resolve the task configurations, namely the selected JIRA instance. This action takes place in the master agent, since is the one which holds the plugin configurations.

This action is only executed if the current job has xray tasks. However, a log message is always presented to the user, saying that the Xray action is being executed. 

This message should only be presented if there is Xray tasks in the current job.
