never 'warn if out of date' setting is ignored

Setting a modules 'warn if out of date' setting to never does not prevent emails from being sent if a module is 'Not Supported'.

I recently discovered this when the jstools module discontinued its support for the 5.x branch. Setting this modules 'warn if out of date' setting to never and am still receiving emails about this module.

I looked in the code a bit and got to update_status_calculate_project_data() and noticed that execution never makes it to line 1113 where the projects 'warn if out of date' setting is checked. I didn't have the time to continue searching through to find out why this is the case.
