Wrong 'pwd' while launching tests in debug mode

[tuxfede]

If you try to debug a test using the sidebar icon, the working directory is set to 'sourceDir' if 'test.workDir' is not available:

vscode-meson/src/tests.ts

Line 281 in af5d9fc

cwd: test.workdir || sourceDir,

However, Tasks.ts uses 'buildDir' as default working directory (as expected).
