OSGi Test Launcher (JUnit) fails when launched from run history fails after renaming test class

[gamerson]

version: 3.4.0-RC1+

If you launch a osgi test run configuration once, then rename a Test class and then relaunch the same configuration (from run history) it will fail because in the launch configuration settings it has persisted the old class name and the bnd.junit.Activator fails to find the stale class name.

Steps the reproduce:

1. create new enroute workspace
2. create new test bundle from wizard
3. Right click test bundle project and choose `Run as > Bnd OSGi Test Launcher (JUnit)

You will see green

4. rename the ExampleTest class to something else FooTest
5. Relaunch the existing "run launch" first Run history menu

You will get an error saying that it can't find test class ExampleTest
