[wix-devs] 5980 - ResolveSource not working

I updated the issue with my findings. Apparently Windows Installer doesn't
allow programmatically resolving source, so I assume v3 added
INSTALLUILEVEL_SOURCERESONLY to give the user the chance to resolve it and
subscribes to the INSTALLLOGMODE_RESOLVESOURCE just out of curiosity.

How should Burn prevent the combination of a NULL hWnd from Apply and
setting the internal UI level to INSTALLUILEVEL_NONE |
INSTALLUILEVEL_SOURCERESONLY? Require non-NULL hWnd in Apply? Only allow
NULL hWnd in Apply if no packages have that uiLevel? Automatically remove
INSTALLUILEVEL_SOURCERESONLY from uiLevel if NULL hWnd? Something else?
