[JENKINS-49562] In a sequential pipeline sometimes the job is executed simultaneously in the master and in an agent

I have created a test script "JenkinsfileTest" that use "agent none" as global configuration and a specific agent.

The pipeline only has some checkouts, sleep, and a "sh echo 'hello'". No parallel execution or something similar.

When you execute that script sometimes in the Build executor status appears that the job is executed in the master and in the agent at the same time. Unable to render embedded object: File (Screen Shot 2018-02-14 at 19.50.38.png?default=false) not found.
