Conflicting migrations

[kesara]

357 and #356 created two different migrations under ietf/snippets/migrations with the same migration number iteration: 003.

This is producing an error: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0003_alter_workinggroup_list_subscribe, 0003_person_slug in snippets).

@mgax, on my local machine I still can't run migrations from #356.

What a mess. It looks like I was a bit too cavalier with https://github.com/ietf-tools/wagtail_website/pull/356/commits/452ba46ffee3c99a1c5e4d5ea3fa45cf482eea33, sorry. #366 should fix it.

No worries.Thanks for the fix.
