Merge lp:~rharding/launchpad/store_edit_product_info_type into lp:launchpad

[Richard Harding]

Implement updating based on changing the information type on Product edit.

= Summary =

This is the second branch in allowing edits to the Product. It updates the
setter for the information type to update policies as required.

== Pre Implementation ==

Talked with Aaron about updating the policies correctly.

== Implementation Notes ==

The first update is to change the validation to make sure we allow the
_setLicense to create a commercial subscription if we've not had one
previously. This allows for a Public project to go to a Private information
type as an edit.

The second update makes sure that after we change the information type that
any policies are updated as required.

== Q/A ==

Create a new project, as a public information type, and then after you create
it go to the "Edit details" and change it to a Private type. It should adjust
accordingly and show as Private.

Create a new project, as a private information type, and then change it to
Public and it should.

== Tests ==

test_product.py

== Lint ==

Cleaned up a couple of lint errors from this and previous branch.
