Not passing passThroughHeaders into options of mount results in Error

[tw00]

Not passing passThroughHeaders into mount(..., { passThroughHeaders: [] }) results in the following error:

node_modules/graphql-rest-router/Router.js:70
                ? [...this.passThroughHeaders, ...options.passThroughHeaders]
                                                          ^
TypeError: options.passThroughHeaders is not iterable
    at Router.mount (/Users/tw/Projects/curator-stack/api/node_modules/graphql-rest-router/Router.js:70:59)
    at makeGQLRestRouter (/Users/tw/Projects/curator-stack/api/tests/load-test.js:37:6)

Changing

-      const passThroughHeaders = Boolean(options)
+      const passThroughHeaders = Boolean(options) && Boolean(options.passThroughHeaders)

here

graphql-rest-router/Router.ts

Line 95 in 700c1f1

const passThroughHeaders = Boolean(options)

should fix the issue.
