feaure/unique proxy backend base paths

[55]

Closes #1200

Maybe fb21892 is unnecessary.

@brylie please test and review.

This does not seem to give any validation message when a duplicate 'frontend_prefix' is used.

Still can't save API Proxy backend.
@apinf/developers if anyone has time to help me with this.

A check for uniqueness works but in some cases can't submit the form.

[brylie]

I am getting duplicate key errors, perhaps related to data sync from nightly.umbrella.apinf.io.

[brylie]

I cleaned up nightly.umbrella.apinf.io and configured a local instance of Apinf.

When trying to add a new Proxy Backend, the Disable API Key field appears to malfunction (in Firefox 50.0a2):

Perhaps start a fresh branch from the latest develop, and add your changes there.

[brylie]

I am able to add a Proxy Backend from Chromium, so we seem to have a Firefox bug related to the Disable API Key field.

The uniqueness check appears to work in Chromium browser, but there is no User Interface message. I see this in the Chromium console:

errorClass {error: 409, reason: "WriteError({"code":11000,"index":0,"errmsg":"E1100…-aa49-40363121cf57"},"_id":"baahyt4AK9w5f9k3L"}})", details: undefined, message: "WriteError({"code":11000,"index":0,"errmsg":"E1100…40363121cf57"},"_id":"baahyt4AK9w5f9k3L"}}) [409]", errorType: "Meteor.Error"}

Also, the form fields are reset when this error occurs.
