Windows compatibility with compileConjure task

[vcatalano]

What happened?

When attempting to run compileConjure from a Windows 10 machine with IntelliJ, our team receives the following stack trace:

Failed to generate conjure IR. The command '[C:\conjure-java-example\recipe-example-api\build\conjureCompiler\bin\conjure.bat, compile, C:\conjure-java-example\recipe-example-api\build\conjure, C:\conjure-java-example\recipe-example-api\build\conjure-ir\recipe-example-api.conjure.json, --extensions, {"recommended-product-dependencies":[]}]' failed with exit code 1.

To reproduce this issue, you will need to clone the current Conjure Java example project (https://github.com/palantir/conjure-java-example) and attempt to run the compileConjure method with IntellJ or Windows Command Prompt.

It appears that the --extensions option is not being parsed properly by the ConjureCli.java class: {"recommended-product-dependencies":[]}

What did you want to happen?

We expect the Conjure library to be compatible with Windows 10.
