commerce 7.x-1.7

This is a minor maintenance release primarily pushed to fix the regression in Commerce 7.x-1.6 that prevented product image fields injected into node displays from linking to their node displays (as opposed to the product admin URLs). The release also addresses minor issues in the checkout pane settings form and checkout form validate / submit handlers.

Changes since 7.x-1.6 (10 commits):

• #1968712 by Berdir: reset the order object stored in the checkout form form cache so a submission that fails validation will ensure the form gets rebuilt with the updated order object.
• #1977984 by dpolant: load the order afresh when processing a checkout form back button submission.
• #1968718 by rszrama: check for a valid entity URI before attempting to use it in the arguments for the Add to Cart form display formatter.
• #1980498 by maciej.zgadzaj: use hook_query_TAG_alter() to identify hook implementations instead of using the tag name itself.
• #1980410 by pcambra: update checkout pane settings form submission to ignore form elements that don't have a type.
• #1970482 by rszrama, davidwthomas: fix the regression introduced by #1863776 into commerce_product_reference_commerce_product_uri() that prevented product image / file fields from linking to the entity into whose display they were being injected; specifically this makes injected product image fields able to link to the product displays that reference them again.
• #1469806 by bkonetzny: add module tags to all our default rule configurations.
• Remove a leftover debug message from the customer profile checkout pane form builder callback.
• #1969156 by rszrama: add query tags to the can delete queries for customer profiles in the Order module and products in the Product Reference module.
• #1967262 by rszrama: update commerce_product_reference_entity_view() to not attempt to find a default product in a product reference field with no value.
