Improve Wipe Out Workspace label

[mpailloncy]

A small precision in the label "Wipe Out Workspace".
I'm sorry but I'm not able to improve this label in all languages.

This pull request contains only label value changes on sidepanel*.properties files.
Why the build is unstable ?
Looks like a problem with "Publish JUnit test result report"

Apparently AbstractProjectTest was hardcoding the English label. It should be fixed to load the message from sidepanel.properties instead. (Note that there are two places where it is using this text; one is expected to fail, but in your branch is failing for the wrong reason.)

Thanks. I don't found any example to load the label in jenkins-test-harness.
Is there an existing way to load it properly ?

Probably just ResourceBundle.getBundle would suffice. Do not recall having ever had to do this.

Sorry, I thought I had made ​​a mistake with a merge so I decided to create another pull request but I could continue with this one ...
Thank you for your help again !
