Remove unnecessary surefire excludes

[svettwer]

The maven-surefire documentation states:

By default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns:

* "**/Test*.java" - includes all of its subdirectories and all Java filenames that start with "Test".
* "**/*Test.java" - includes all of its subdirectories and all Java filenames that end with "Test".
* "**/*Tests.java" - includes all of its subdirectories and all Java filenames that end with "Tests".
* "**/*TestCase.java" - includes all of its subdirectories and all Java filenames that end with "TestCase".

Therefore it's not required to exclude (^IT.*|.*IT)\.java tests in the configuration.
