Remove excludes for maven test execution.

Maven Surefire and Failsafe plugins by default do not run inner classes, no matter if they are `@Nested` or just plain static inner classes.

This change removes this default exclude.

Closes #1627
See https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#excludes
