Fixes #893

After two stupid mistakes I now arrived at the failures I experienced before pushing. One test case fails, and I canot understand why. I certainly can do the following:

qualified_root> pwd
/Users/sydow/acton/compiler/test/actonc/project/qualified_root
qualified_root> actonc build --root test.main
Building project in /Users/sydow/acton/compiler/test/actonc/project/qualified_root
Compiling b.act for release
Already up to date, in 0.001 s
Compiling test.act for release
Already up to date, in 0.000 s
Building executable out/rel/bin/test

which seems to me to be the test that fails. I can't get further with this.

The test is wrong. The function buildThing checks if a "thing" is an acton project or a single .act source file and builds accordingly. If it's a project, it compiles the project by running actonc build, i.e. buildThing adds the build argument and sets the working directory to the project.

In this case, the test case itself sets arguments to build --root test.main so the final cmd args to actonc become build build --root test.main.

I squashed the two extra commits... and added a fix.
