Cannot upload images to products

Issue Description

If you attempt to upload an image to a product you receive the following error on both the server and the client:

Exception while invoking method 'FileCollection/INSERT/Media' Error: Match error: Expected string, got undefined
    at check (packages/check/match.js:35:15)
    at Object.getUserShopId (server/api/core/core.js:444:5)
    at Object.allow (server/startup/collection-security.js:50:33)
    at _.every.restriction (packages/ongoworks:security/lib/server/Security.Rule.js:84:37)
    at Array.every (<anonymous>)
    at Function._.every._.all (packages/underscore.js:253:62)
    at Security.Rule.js.Security.Rule.allow (packages/ongoworks:security/lib/server/Security.Rule.js:61:14)
    at _.any.rule (packages/ongoworks:security/lib/server/Security.Check.js:91:38)
    at Array.some (<anonymous>)

Steps to Reproduce

1. Create a product and publish
2. Attempt to upload an image
3. Observe the Match error on both server and client

I think I see the issue. In https://github.com/reactioncommerce/reaction/pull/3510/files, the changes in collection-security.js are using this.userId when they should be using userId.
