Expected behavior: The getVersions(projectID) method should only return versions from a specific project.

Current behavior: The method is returning versions from multiple projects, even though it is passed a specific projectID.

Library Version: redmine-java-api 3.1.2

Description: When using the getVersions method with a specific projectID, the returned list of versions contains versions that belong to other projects, which is not the expected behavior.

Code snippets:

`@Override
public Sprint getSprintByName(String projectKey, String sprintName) throws IssueTrackerException {
try {
Project project = manager.getProjectManager().getProjectByKey(projectKey);
List versions = manager.getProjectManager().getVersions(project.getId());

    for (Version version : versions) {
        if (version.getName().equals(sprintName) && version.getId().equals(project.getId())) {
            return new RedmineSprintBuilder(version).build();
        }
    }
    throw new NotFoundException("version not found in project '" + projectKey + "'.");
} catch (RedmineException ex) {
    throw new IssueTrackerException("");
}

}`
