Root cause: https://github.com/microsoft/vscode-java-test/blob/master/java-extension/com.microsoft.java.test.plugin/src/main/java/com/microsoft/java/test/plugin/util/TestSearchUtils.java#L185-L189

We are using the search engine to search all the test items but the search engine does not support search the annotation hierarchically. That's why meta annotations are not able to be found.
