version 5.8.0 breaking authentication and GraphQL API queries

[myworks-peter]

Issue summary

We just auto-updated to v5.8.0 in a standard deploy last night, and then noticed that all of a sudden we were having both session/authentication issues with our embedded app in Shopify, as well as issues with GraphQL queries failing inside of our app.

After an extreme amount of troubleshooting, we realized that hardcoding v5.7.0 of this library in our app resolved the above issues.

Expected behavior

Not breaking API calls

Actual behavior

• Authentication/session issue in Shopify resulting in embedded app not loading within Shopify; with a 401 Unauthorized error in the console
• GraphQL API queries resulting in a 400 Bad Request message from Shopify;
• The below error occurring:
  Syntax error {"exception":"[object] (JsonException(code: 4): Syntax error at /var/app/current/vendor/shopify/shopify-api/src/Clients/HttpResponse.php:48)

Steps to reproduce the problem

1. Create a basic installation of the php template following the instructions here: https://github.com/Shopify/shopify-app-template-php
2. Try to run the project.
