Add some HTTP tests and make some fixes to axios request handling

[brandenrodgers]

Description and Context

Major changes:

• Added some tests for the HTTP files
• Using mockResolvedValue where applicable because it's simpler
• Axios contains the error status code in err.status, not err.statusCode
• Axios takes in posted data in config.data, not config.body

Who to Notify

Everything looks good but you have an extra path/to/local/file kicking around. Not sure if that's left over from earlier or if your getOctetStream test is still creating it and not cleaning it up
