Simplify and correct FileSystemTests eclipse-platform#783
Several test classes extend the FileSystemTest. This class only provides some utility functions and always creates a local and an in-memory file store, even if the actual test does not need it. This change simplifies the test classes by removing the FileSystemTest super class. The necessary utilities are moved to a utility class. The file store creation logic is moved to an according JUnit test rule that can be instantiated for a local or in-memory file store and keeps track of setup and teardown. This also fixes a bug in interwoven, inherited setup and teardown functions (eclipse-platform#783) Fixes eclipse-platform#783.
