MOTECH-980 Fix Commcare messing with web-api controller

This commit fixes (hopefuly) an issue, that caused Commcare messing up
with the web-api Permission Controller - The web-api would retrieve json
from Commcare's permission mapping and vice-versa.
Both Commcare and web-api defined an angular service named Permissions,
what probably was the root cause of problems.
