(Originally reported against pact-js here)

If the consumer or provider names contain single quote characters, the pact mock server doesn't spin up correctly, and connections are refused.

I've provided a branch that illustrates the problem in the Jest example for pact-js:

 git clone git@github.com:TimothyJones/pact-js.git
 cd pact-js
 git checkout single-quote-issue
 npm i && npm run dist && cd examples/jest/ && npm i
 npm run test

This happens because we escape the arguments here.

This escaping is necessary because we concatenate arguments to a single string here.

If we instead passed arguments as an array,child_process.spawn() will correctly escape them (docs here). However, windows quoting isn't straightforward (which might be why we started doing the quoting in the first place).

It looks like the cross-spawn package would work as a replacement for child_process that is better for Windows.

I haven't provided a PR because I don't have a windows machine I can test on - but I'm happy to roll one up if someone else is able to test it.
