Clean shared state pollution to avoid flaky tests.

[LALAYANG]

Link to issue: #8390

What is the purpose of the change

This PR is to fix a non-idempotent test org.apache.dubbo.rpc.filter.ExecuteLimitFilterTest.testExecuteLimitInvokeWitException

• The test does not remove RpcStatus after running, which pollutes the state shared among tests.
• 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.

Brief changelog

Removes the status of RPC when the test ends.

Verifying this change

With the proposed fix, the test does not pollute the shared state (and passes when run twice in the same JVM).
