Command expansion upload fails on Windows

[parkerabercrombie]

@colin-lewis-19 reported an error when using aerie-cli to upload command expansions to Aerie from a Windows machine

Running this command failed with an error about a missing parameter:

 aerie-cli expansion deploy -m 278 -p 169 -c dist/0.0.0-dev0/config.json --time-tag --rules-path dist/0.0.0-dev0/expansion

But this command worked:

aerie-cli expansion deploy -m 278 -p 169 -c config.json --time-tag --rules-path expansion/

I was not able to reproduce on a Mac, so could be something platform specific.

Aerie CLI version 2.10.0
