Thanks for the rewrite and a revamped report in the pytest-html!

I noticed that the collection errors are not reported as part of pytest-html v4 but they were reported till pytest-html==3.2.0

Reproducer:

test_sample.py

import pytest

raise ImportError("Non existent module")

Run:

pytest test_sample.py --html=~/tmp/generated_html.html

pytest-html == 3.2.0:

pytest-html == 4.0.3rc0:

Looking at the codebase, I can see that pytest_collectreport got missed out during the rewrite, so maybe adding that back should fix this.
