Fix system profile behavior

[mkolegan]

System profile was not read from xml because the logic fallbacks to realData.

In addition to PROFILE_USER and built-in resource-based profiles we need to check PROFILE_SYSTEM

I wonder, could we put these checks directly inside getProfileResId, so the caller doesn't have to care?
To avoid future problems.

Thanks @mkolegan

@ale5000-git getProfileResId really only does that (getting the ressource id of the profile if it is a built-in profile). One could probably also check for hasProfile() here instead, but for now this solution is safe and works.
