Make tests working even if you have initialized gitflow on the project

Ok I found the issue. In fact using in our pom we always define this:

<plugin>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>${surefirePluginVersion}</version>
          <configuration>
            <systemPropertyVariables>
              <java.io.tmpdir>
                ${project.build.directory}/surefire-workdir
              </java.io.tmpdir>
            </systemPropertyVariables>
          </configuration>
        </plugin>

So tests are executed in a directory inside the project, and when it tries to find a repository it goes up to the first git directory found (here the project it-self).
