v0.3.5: readBody tries .json() without clone() first

Some test mocks expose .json() but not .clone() — cloning throws on
object mocks. Try .json() directly, fall back to .text(). Real Response
objects are unaffected (calling .json() twice would throw, but we only
call it once since we're on the error path).
