"Could not fetch targets" when a test has no suites

[jameswestman]

If you leave the suites argument of a test empty, meson defaults to putting the test in a single suite named after the project name, but if you set the suites argument to an empty array, meson leaves it empty. The createTestTask function in tasks.ts does not handle this case, since it uses the first suite to get the project name, so you get a "Could not fetch targets" error with no further information in the output panel.

I think this could be solved by getting the project name from intro-projectinfo.json instead?
