Describe the Bug
Allure report doesn't take in correct number of tests when using parametrized tests where tests parameters are duplicated.

Steps to Reproduce

1. Create a Python virtual env
2. Install allure-pytest
3. Create example tests to reproduce:

import pytest

@pytest.mark.parametrize(
'a, b',
[
(1, 1),
(1, 1)
]
)

def test_one(a, b):
assert a == b

4. Run tests using pytest --clean-alluredir --alluredir=/tmp/allure-results
5. Generate allure report allure generate /tmp/allure-results/ --clean --output /tmp/allure-results/allure-report --single-file
6. Open Allure report

Expected Behaviour
The report is generated without errors and the report shows 2 tests.
