[REG 3.2.2 -> 3.3.0] Creator does not detect Qt version from PATH

1. Add the path to qmake.exe to your system's PATH variable.
2. Start Creator with empty settings, e.g. by passing a non-existing path using the parameter "-settingspath".
3. Go to "Tools" -> "Options..." -> "Build & Run" -> "Kits".
   There's a kit named "Desktop" which does not have a Qt version.
4. Go to "Tools" -> "Options..." -> "Build & Run" -> "Qt Versions".
   There is no Qt version set up.

Creator should automatically detect a Qt version from the system's PATH variable and set it up in "Build & Run" settings. Creator 3.2 did this correctly.
