Core and bundled module versions are not handled correctly

(ticket description written by djazayeri)

See LOGIC-100.

There is something wrong at the intersection of core module versions, bundled modules, and the initialization wizard.

According to James, the way to reproduce this should be:

• Run 1.8.3, using the version of logic that comes bundled with it.
• Upload a newer version of the logic module (0.5.2) via the web interface.
• Restart tomcat.
• At this point, OpenMRS startup should fail, asking you to upload the logic module
  • TO DO: investigate why OpenMRS isn't seeing/accepting the new Logic version (0.5.2) at this point.
• If you upload logic 0.5.2, it's rejected
  • TO DO: investigate why it's rejected at this point. (Probably the same answer as the previous TO DO)
  • TO DO: check whether this has caused multiple versions of logic in the .OpenMRS/modules folder. Determine if we should really be deleting some of them; or maybe this will happen automatically once we recognize 0.5.2 as being > 0.5.
• If you then upload logic 0.5.0.1, things should start up, with logic 0.5.2 running, and multiple logic omods in the modules folder.
