Project information is wrong when listing unscoped stacks.

[andersonvom]

When using the unscoped list of stacks, the project information is being retrieved from the context, instead of each individual stack, making it seem like all stacks belong to the user issuing the call. They should use the information already in the stack instead.

    Stack identity reads tenant from stack not context

    This refactors the way stack identity reads tenant_id information so
    that it uses the information already in the stack, instead of getting it
    from the context every time.

    This allows for unscoped list of stacks to show correct project
    information (the project that each stack belongs to), instead of the
    current one in the context.
