Pseudopattern json leaking into base patterns

[bmuenzenmeyer]

I am using Pattern Lab Node v3.0.0-alpha.10 on Windows, with Node v8.9.3, using a Gulp Edition.

Expected Behavior

data.json

{ "data": "World" }

button.mustache

<button>Hello, {{data}}</button>

button~moon.json

{ "data": "Moon" }

Both buttons should display unique destinations

Actual Behavior

both buttons display Hello, Moon
