Project edit view can't find the default archiver

I've seen this too (so confirming).

The ProjectCreateView class has this override for get_context_data:

    def get_context_data(self, **kwargs):
        """
        Supplement the project view with an archive check
        """
        context = super(
            ProjectCreateView, self).get_context_data(**kwargs)

        archive = get_default_archive()
        if archive:
            context["archiver"] = archive

        return context

I can clearly see it's getting the default archive information. Interestingly, ProjectUpdateView doesn't have this, so I'm pretty sure it's just needs to get the default archive and set "archiver" in the context.

The alert is displayed by a tiny include "projects/missing_archiver_alert.html" which only needs that "archiver" item set in the context so I think we're good to get this fixed.

My only extra request is to first add a failing test for this, then apply the fix :) but that goes without saying.
