Test Explorer is not reporting test status if a test is annotated with xdist_group

[rsporny]

Type: Bug

Behaviour

Test Explorer is not reporting test status (red/green/skipped icons) when executed test is annotated with @pytest.mark.xdist_group("<group_name>")

Steps to reproduce:

1. Have pytest and xdist installed.
2. Create a test:

import pytest
@pytest.mark.xdist_group("my_name")
def test_result_on_test_explorer_tab_with_xdist_group():
    assert True

3. Setup pytest args

-n1 --dist=loadgroup

4. Run the test in Test Explorer pane.
