ShowInContextMenu UI tests have initialization error - missing server requirement

When test is being run in context of jenkins job, it got error:

org.junit.runners.model.InvalidTestClassError: Invalid test class 'org.jboss.tools.as.ui.bot.itests.parametized.server.ShowInContextMenuTest': 1. null

Problem is that former design when the test was run alone with special requirements.json file all was alright, but now the file is being "overridden" in allTestsSuite job because it uses different (jre.json) requirements file. It is needed to include reddeer requirement from former (wildfly-requirement) file into jre.json.
