Regression: 'Default build directory' option is ignored

I set the next default build directory (Tool > Options > Build & Run > General > Build and Run > Default build directory):

../%{JS: Util.asciify("build/%{CurrentProject:Name}-%{CurrentKit:FileSystemName}-%{CurrentBuild:Name}")}

But when i opened existed qbs project without .user file, Qt Creator ignores this change and suggests the next path:

D:/path/to/projects/build-some_project-Qt_5_12_1_msvc2017-Debug

instead of

D:/path/to/projects/build/some_project-Qt_5_12_1_msvc2017-Debug
