mock: improve validateReplyParameters

[Uzlopak]

if you would set responseOptions to null, it would pass but then it would throw an error in createMockScopeDispatchData because it would try to read headers attribute from null.

undici/lib/mock/mock-interceptor.js

Line 96 in fedae35

const headers = { ...this[kDefaultHeaders], ...contentLength, ...responseOptions.headers }

[Uzlopak]

data can never be undefined because it is always set to empty string

undici/lib/mock/mock-interceptor.js

Line 151 in fedae35

const [statusCode, data = '', responseOptions = {}] = [...arguments]
