Fix rename scenario for Internet Explorer

[caseycesari]

Overview

Using _.curry appeared to call the validate function before it needed to
be called, which resulted in a JS error and prevented the modal from
being displayed. Keeping the correct scope for the validate function is
slightly reworked here so that _.curry does not need to be used, which
lets things work as expected in IE.

Connects to #2315

Demo

Testing Instructions

• Create a new project and add a scenario.
• Try to rename the scenario to a valid name. It should work.
• Try to rename the scenario to a name that already exists. It should show an error message.

Heads up, a few of the tests broke

Thanks. Just pushed an amended commit to address the test failures.

[arottersman]

+1, working as expected on IE11 and all other supported browsers.

[arottersman]

Don't think we should change it, but could we have also moved this method onto the ScenarioModel and avoided the binding?

[caseycesari]

Yeah, totally. I think that would work as well.

[caseycesari]

Thanks for the review.
