After upgrading to 0.7.6, the few tests I have that used `assert.calledWith` started failing, all with this stack trace:
Error: Chrome 30.0.1599.101, Mac OS X 10.8.5 App app.fetchPortfolios() registers event handlers to automatically switch portfolios when added or removed

I think this may be down to some kind of version mismatch for the module 'samsam', but it's confusing as hell to debug. I have 1.0.1 installed under buster/node_modules, and 1.1.0 under buster/node_modules/formatio/node_modules.
