Updating a model using `through` results in 400 error if collection attribute is updated

[AskYous]

Sails version: 0.12.1
Node version: 6.9.2
NPM version: 3.10.9
Operating system: Windows 10

It seems that when two models are related via a many-to-many relationship using the through attribute property, and one of the models is updated via HTTP PUT, having the attribute using the through updated as well, sails throws a 400 error.

I've created a repository that reproduces this error. Please read the README.md file there. This is my repository that reproduces this error:

Hi @AskYous, thanks for posting. This has been patched in Waterline 0.11.8. If you re-install Sails (either globally or for your local project) it should pick up the new Waterline version.

Hello @sgress454, I uninstalled SailsJS globally and locally, but I still experienced the same error. The error on the repository I linked above still gets thrown. Can you please check? My sails version is 0.12.11.

@sgress454 I don't know why but it works now (but wasn't before). Thanks for the update!
