Only push directory if we find a MO INI file

Only push directory if we find a MO INI file.

---

Open points:

• I figured having a debug log here would be useful in troubleshooting
• I could not find any OS-independent way of joining paths via Qt, do we have something like this that I should be using instead of the hardcoded path joining (taken from the same file)
• Do we still want the filter code if this lands?
• I did a compare against case-sensitive ModOrganizer.ini, can this possibly cause issues that warrants needing a full path lowercase comparison?

You can probably remove the filter parts if we're checking for the INI file. You can use the following to check for the existing of the INI if you don't want to use a hard-coded /:

const QFileInfo iniFile(QDir(d), "ModOrganizer.ini");

if (iniFile.exists()) {

}

Done, removed the filter setup.
Had to expand d first, as it was only a path component based on the game's name.
