[Fixes #3032] When OrderInventory#verify is given a specific shipment, only remove variant from that shipment
Test to display order number when order is shown
Less obfuscated check for order#completed? [Fixes #3034]
Reload shipment after removing variant item via api

Fix broken spec on api build. The item was being removed properly but
the controller still returned the old obj instead of the new one with
the item removed
Force select2-rails to 3.2.1

select2-rails 3.2.2 breaks all capybara helpers in Spree that depends on
the label tag for attribute. e.g.

    <%= label_tag :add_variant_id, Spree.t(:name_or_sku) %>

    Instead of:

    <label for="s2id_add_variant_id">some text</label>

    will generate:

    <label for="s2id_autogen1">some text</label>

see https://github.com/ivaynberg/select2/commit/519070b11da9347cf1542d26fc59a83b0c3fd934

wtf select2 ..
