Test Explorer unpack parametrize tests

[Wintreist]

Type: Bug

Behaviour

Expected vs. Actual

Tests marked parametrize are expected to be collapsed to the test name, and if you expand them, then there are tests with specific parameters inside them

Test Explorer expands tests marked paramterize

Steps to reproduce:

1. Create the file test_something.py
2. insert the following code into it:

import pytest
class TestSomething:
    @pytest.mark.parametrize("arg", [1, 2, 3])
    def test_one(self, arg):
        pass
    @pytest.mark.parametrize("arg", [1, 2, 3])
    def test_three(self, arg):
        pass
@pytest.mark.parametrize("arg", [1, 2, 3])
def test_two(arg):
    pass

3. With the test_two function the test explorer behaves as it should, but with functions inside a class it doesn't, the same behavior is expected for functions inside classes as well
