Vicky's merges for src/middleware/render.js from Project 1 and tests from tests/middleware.js

[vickyc2266]

Reduced cognitive complexity of the renderMethod which is within the processRender function of the render.js file by taking away a conditional that appears in the code more than once and putting it into a helper function with an intuitive title called checkHeadersSent(res). The function here is supposed to provide the same exact logic as the original code but just putting it in into a function and calling that function where it is needed.
