Let search engine look into AbstractProject instead of FreestyleProject only

[thomasnemer]

Fix search engine not returning anything else than freestyle projects

Search engine only returns FreestyleProjects, this does not include other types of job like MavenProjects.
This PR intends to change this behavior to include all AbstractProjects in search results

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue (Couldn't find a way to create a MavenProject using JenkinsRule)
