Json-ify any non-string object in #to_return_json

[inkstak]

When using to_return_json, it allows to pass an Array body.
By extension, it'll convert any non-string object passed to :body parameter to json.

stub_request(...).to_return_json(body: [{abc: "def" }])
stub_request(...).to_return_json(body: Record.find(1))

Love this!

Any chance it can be extended to accept procs also? It's a jarring inconsistency that to_return can accept a body: -> {} lambda but to_return_json doesn't.

Rather disappointing that in order for the stub to trigger any side effects, we have to drop out of to_return_json and lose the header/body niceties.

Added to the PR:

stub_request(...).to_return_json(body: ->{ Record.find(1) })
