[SUREFIRE-1880] Run nested junit test from abstract class

**[jakob braun](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=jakob.braun@exasol.com)** opened **[SUREFIRE-1880](https://issues.apache.org/jira/browse/SUREFIRE-1880?redirect=false)** and commented

 

Consider the following Junit5 tests:

```java
abstract class AbstractTest{

@Nested

class NestedTest{

@Test

void myTest(){

}

}

}

class TestImpl extends AbstractTest{

}
```

I would like to run myTest. It seems however like this is not possible using the failsafe plugin.

Here is what I tried:
* AbstractTest$NestedTest.myTest
* TestImpl$NestedTest.myTest
* AbstractTest$NestedTest#myTest
* TestImpl$NestedTest#myTest

If I'm doing something wrong I would be glad about some help!

**Affects:** 3.0.0-M3, 3.0.0-M5

Start by reproducing the Failsafe behavior with the abstract and nested JUnit 5 classes shown in the issue. Try the four listed selectors and inspect how the plugin discovers or filters the inherited nested test. Done means myTest can be selected and executed from TestImpl, with regression coverage for this example.
