Generated Postman is invalid against their 2.1.0 spec

[philsturgeon]

I'll fix whatever the problem ends up being, but right now I'm getting so many errors that the postman collection generated with API Flow is failing to upload.

Tested against Postman Collection v2.1.0 http://schema.getpostman.com/?_ga=2.73374291.1338367236.1512580333-921490803.1512580333

Actually a fun way to test this, take the content from your https://github.com/luckymarmot/API-Flow/tree/master/testing/e2e/internal-postman2/test-case-0/output.json and run it through http://json-schema-validator.herokuapp.com/ with their schema. It has loads of errors and warnings.

I'll fix a few now, including the fact you cannot have null for headers, it's got to be a string!

#154 ensures it's following the v2.0 spec, and that's good enough for me. I'll add in v2.1 support separately.
