Trigger sorting for initial sort column

[wanam]

Currently it only sets the toggles for initial sort columns without actually doing the sorting.
This fixes #247

Would you mind adding a test for the sort? @wanam

[wanam]

I think it is not necessary to create a new test, it's already covered by this one: https://github.com/pytest-dev/pytest-html/blob/master/testing/test.js#L26

[BeyondEvil]

Hmm... Does the test fail if you revert your change? 🤔

If not, the test needs to be updated right? @wanam

[wanam]

The test will still succeed with/without my change, because the 'initial-sort' falg is default set (hard coded here https://github.com/pytest-dev/pytest-html/blob/master/pytest_html/plugin.py#L425) on the first column (test result), if we set this flag for another column, the current test won't pass without my change.

@wanam

Ah, I see. Well, I don't want to change the default.

Is it possible to create a new test then based on the scenario in #247 ?

One that will actually fail without your change, without having to change the hard coded default.

@BeyondEvil
To do such scenario, we need to clone js_test_report.html with 'initial-sort' flag set for another column, because this flag needs to be set before running the init on main.js.
Is it ok?

[BeyondEvil]

Oh yeah you're right. Sorry about that.

It's not enough to clone it, you'll have to fiddle with the Gruntfile as well, so let's skip it.

Thanks for the PR! 🙏

LGTM!
