gp_create does not fail when npx command fails

[layik]

> gp_create(tempdir())
/usr/local/lib
└── create-react-app@1.5.2 

Initializing project at: /var/folders/z7/l4z5fwqs2ksfv22ghh2n9smh0000gp/T//RtmpTJV92H
Could not create a project called "RtmpTJV92H" because of npm naming restrictions:
  *  name can no longer contain capital letters
To build/run app, set working directory to: RtmpTJV92H
Standard output from create-react-app above works.
You can run gp_ functions from directory: RtmpTJV92H
To build the front end run: gp_build()
To run the geoplumber app: gp_plumb()
Happy coding.

Reprex ignore the system outputs hence, not reprex'ed.
