Streamline updating invoice addressee

[vohmar]

Creating a billing profile and assigning billing profile to an invoice are two separate processes.

There is a "change billing profile" button in the invoice view redirecting user to edit your invoice view
If user does not have billing profile already created next step would be pressing "create new billing profile" button
That button takes user to "create a billing profile" view (/billing_profiles/new), but after submitting the new profile data the new profile is not assigned to the invoice user was editing. Instead user is redirected to the detail view of newly created profile and from there user need to navigate back to the invoice and once again press "change billing profile" to be able to select the prepared profile from the drop-down and submit it.

We need to change this so that if user starts the navigation from an invoice view: "change billing profile" - "create new billing profile" the newly created billing profile is automatically assigned to the invoice.
