Fix xod/core/select description and add test patch

[brusherru]

But we have a problem to write such tests in the same library because tabtests will get an error:

CONFLICTING_SPECIALIZATIONS_FOR_ABSTRACT_PATCH {"patchPath":"xod/core/if-else","conflictingSpecializations":["xod/core/if-else(number)","@/if-else(number)"],"trace":["tabtest/local/test-select-4-numbers","@/test-select-4-numbers…

So probably we have to extract such tests into separate xod/test-core? 🤔
Also, in this case, will be no problems with position of defers in the program graph :)

I can’t suggest anything constructive straight away, but I’d like to note that the problem is deeper than the choice of where the test should reside. This is related to #888 as well. The problem is when we have a library opened as a project. At this time we effectively have the contents loaded twice. A poper solution should address the library development experience.

But until we have no solution, a separate project test-core sounds reasonable. But, please, do not pollute userspace with it. Create it under ./workspace/test-core, not under ./workspace/__lib__/xod

They should be under CI, but they are not currently:

  test-cpp:
    docker: *docker-custom-nodejs
    environment:
      XOD_OUTPUT: /tmp/tabtests-cpp
    steps:
      - checkout
      - restore_cache: *restore-node_modules
      - run: *step-install
      - run:
          name: Build CLI
          command: yarn build:cli
      - run:
          name: Generate tabtests
          command: | # --------------------- here
            ls -d workspace/__lib__/xod/* | xargs -n 1 \
              yarn xodc tabtest --no-build | cat
      - run:
          name: Build tabtests
          command: make -C $XOD_OUTPUT
      - run:
          name: Run tabtests
          command: make -C $XOD_OUTPUT test

Should be:

ls -d workspace/__lib__/xod/* workspace/test-core | xargs ...

And if so, would it better to put the test under a common subdirectory (workspace/test?) to avoid touching the config in future?!
