Wrong returning content type of "text/plain" on /templates path

[JaysonBH]

Notifications is returning the wrong content type of "text/plain" on http://notifications.$CF_APP_DOMAIN/templates path where it should be "application/json" since it is sending json output.

This is causing browsers and the uaac from formatting the output correctly.

Example:

uaac curl -k https://notifications.$CF_APP_DOMAIN/templates -X GET
GET https://notifications.$CF_APP_DOMAIN/templates

200 OK
