[MNG-5952] Integration tests should not be language dependent

**[Harald Wellmann](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=hwellmann)** opened **[MNG-5952](https://issues.apache.org/jira/browse/MNG-5952?redirect=false)** and commented

Some integration tests (e.g. `MavenITmng3477DependencyResolutionErrorMessageTest`) are language dependent and may fail when the system locale is not English (my default locale is de_DE.UTF-8).

Preferably, the tests should not require a particular language setting at all, or they should verify this prerequite and fail fast.

For the short term, it would help users if this prerequisite were documented in http://maven.apache.org/core-its/core-it-suite/ and `maven-integration-testing/core-it-suite/pom.xml`.

Start with MavenITmng3477DependencyResolutionErrorMessageTest and inspect maven-integration-testing/core-it-suite/pom.xml, along with the core-it-suite documentation. Run the affected integration test under a non-English locale and determine whether it can avoid language-dependent assertions or must document and verify the prerequisite. Done means the locale issue is handled consistently and the prerequisite is documented if still required.
