Build error in ./resources/prepublish.sh

[brianwarner]

Running npm install appears to fail on the prepublish workaround. I think I see the issue, though I'm not sure how to fix it, exactly. Here's what I think is happening:

• In the prepublish script, npm_config_argv is used to workaround the issue where prepublish runs on install
• However, npm_config_argv has been deprecated since this fall
• The recommended approach is to use npm_command

Unfortunately I'm not familiar enough with graphql-relay-js to be able to say how to solve this (I just hit it when my trivial documentation PR failed CI), though I do see that prepublish was deprecated, so maybe someone else knows an intelligent way to work around this? @IvanGoncharov, any suggestions?
