INTERNALERROR> AttributeError: 'Config' object has no attribute 'cache'

[whhsu2]

Bug Report

Environment
pytest==8.3.0, pytest-memray==1.7.0

Repro Steps
pytest --memray -p no:cacheprovider gets the error

    if _config.cache is not None:
AttributeError: 'Config' object has no attribute 'cache'

This is due to here:

pytest-memray/src/pytest_memray/marks.py

Line 206 in e2d0aed

if _config.cache is not None:

    if _config.cache is not None:
        cache = _config.cache.get(f"memray/{_test_id}", {})
        previous = cache.get("total_allocated_memory", float("inf"))

Expected behavior/code
Able to run pytest memray without the cacheprovider plugin

Possible Solution
Replace if _config.cache is not None: with if getattr(_config, 'cache', None) is not None:
