test_files: Fix directory_import.qml test
Problem: QDEBUG : TestFiles::testFiles(directory_import.qml) "Warning: Module not found, some types or properties may not be recognized in /home/jenkins/sources/kdevelop/stable-kf5-qt5/languages/qmljs/tests/files/directory_import.qml:[(2,0),(2,47)]: <no explanation> (found by Semantic analysis)" FAIL! : TestFiles::testFiles(directory_import.qml) 'top->problems().isEmpty()' returned FALSE. () Loc: [/home/jenkins/sources/kdevelop/stable-kf5-qt5/languages/qmljs/tests/test_files.cpp(137)] I'm not sure why a module import is tested in a file called 'directory_import.qml'. I also don't know how the QML/JS is supposed to find the kdevplatform module without knowing about its location.
