[472380]Repaired SWTBot tests
Created by: SmithRWORNL
Adds proper dependencies to SWTBot test bundles, allowing them to create Eclipse instances when launched from Maven to run tests in. It also changes PlotEditorTester to use a fake IVizServiceFactory, since Maven does not iniatalize and consume all OSGi services needed for the test.
