Remove ResourceTest#getWorkspace() method #903

The method getWorkspace() in ResourceTest is only a convenience method
delegating to ResourcePlugin#getWorkspace(). In order to clean up the
inheritance hierarchy of ResourceTest for migration to JUnit 4, this
change inlines the delegation.

Contributes to
#903
