DrupalCommerceEntityController::invoke should follow EntityApiController

Hi,
We recently experienced an issue while using rules for updating order statuses reacting to the event "After updating an existing commerce order", our generic entity update hooks weren't fired properly.
After a lot of debugging, we found out that having those hooks fired after Rules could lead to issues (See the quote below and the issue described here #1211946: Invoking entity_save on hook_entity_insert() might cause troubles).
I assume the invoke method of DrupalCommerceEntityController hasn't been updated after the fix, and I think Commerce has to copy that change (http://drupalcode.org/project/entity.git/blobdiff/0e5ae63f144be44b00f2fe...).

To avoid any troubles with invoking entity_save() on hook_entity_insert() we have to make sure Rules operates last - else modules' update hooks might be invoked before their insert hooks.

For that Rules has already a rather high weight, however if modules implement the generic entity hooks they are currently still operating after Rules - as they come after the entity-type specific hooks. To fix, we need to use the generic entity hooks too for invoking rules events.

Entity type providing modules should just invoke the rules-event last. For the entity API we can fix that generally.

Patch following.
