[owocki]

can be tested with

from dashboard.models import Bounty
for bounty in Bounty.objects.filter(current_bounty=True).order_by('created_on'):
    print(bounty.github_url, bounty.is_legacy, bounty.web3_created.strftime("%Y-%m-%d"), bounty.can_submit_after_expiration_date)

but does not seem to be working rn

@owocki @mbeacom I wrote test for this already, they will pass once the pr is merged + 90b4d93 is applied. Currently on master test case test_can_submit_standard_bounty_after_expiration_date_if_deadline_extended fails.

After I cherry-picked the commit from this branch I get.

app/dashboard/tests/test_dashboard_models.py::DashboardModelsTest::test_can_submit_legacy_bounty_after_expiration_date PASSED
app/dashboard/tests/test_dashboard_models.py::DashboardModelsTest::test_can_submit_standard_bounty_after_expiration_date_if_deadline_extended PASSED
app/dashboard/tests/test_dashboard_models.py::DashboardModelsTest::test_cannot_submit_standard_bounty_after_expiration_date PASSED

It is almost midnight here, so I will likely continue on tests tomorrow, just wanted to give a heads up that those codecov values will improve.
