Getting erron when building on Mac

Hi there!

Describe
When I run a build script for Mac got an error

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

After 5 min investigation, found that there is a single file in the demo/node_modules/clone directory. That leads to a positive condition on line 3 and it tries to run an npm script without installed packages.
So I removed the folder and create a PR https://github.com/zoom/zoom-sdk-electron/pull/10

I gave it a second try and noticed that the error doesn’t break the build flow. The only reason I saw it was my internet connection on that moment. Right after that, the script is getting headers for node-gyp and you will see a long-long field of text.
On the next step when you run the demo app it will install scripts and the demo will work.

So it is not a big deal to have that error there. But it is much cleaner to remove the folder.
Feel free to accept or decline my PR
