Check all “save” calls to check the return value is used by a node we have visited.

Review process:
Implementation:
See the best practice details here rails-bestpractices.com/posts/2012/11/02/check-the-return-value-of-save-otherwise-use-save/
and “create” or use “save!”, “update_attributes!”, or “create!”, respectively.
Review all code to make sure we either check the return value of “save”, “update_attributes”
