Reset path to avoid flaky tests

[LALAYANG]

What is the purpose of this change

This PR cleans the state pollued by the test com.vmware.admiral.common.util.ReflectionUtilsTest.testSetPathAnnotation.

It may be better to clean state pollutions so that some other tests won't fail in the future due to the shared state pollution.

Reproduce test failure

Run the test twice in the same JVM.

Expected result:

The tests should run successfully when multiple tests that use this state are run in the same JVM.

Actual result:

We get failure:
Failed tests: ReflectionUtilsTest.testSetPathAnnotation:32 expected:</[foo]> but was:</[bar]>

Why the test fails

The path was changed to /bar.

Fix

Reset the path to /foo.
