PytrizeJumpFixture jumps to start of the line not where the fixture definition starts

I we have this:
```python
import pytest

class TestMyClass:
  @pytest.fixture
  def my_fixture(self): ...

  def test_something(self, my_fixture): ...
```

Executing `PytrizeJumpFixture` over `my_fixture` in `test_something` jumps to fixture definition but col 0.

## Expected

Should jump to the `d` in `def my_fixture(self)`.
