Fixed missing PS resources

[anmenaga]

PR Summary

Fixed regression where PS resources were not shown in the default table view.
There was a 'continue' to the next resource (without displaying) if a resource did not have a manifest attached to it (which is the case for PS resources).
The fix is basically to remove that 'continue;' so that such resources are displayed.

@anmenaga this change seems fine to unblock, but created #356 so that PS resources can show version and method information
