ectypes might not be respecting changes to blueprints within the same lexical scope

[nicholasf]

Test:

• create a mocha test. Create a blueprint and create a blueprint in a beforeEach clause. Then create an ectype. Then, in another beforeEach clause, create the ectype overriding the blueprint with new data.
• ensure that the new data is not within the first ectype.

This problem will go away if you next the beforeEach clauses within each other.
