fix: check `npm.config` before accessing its members
Sometimes, `npm.config` can be missing entirely, but there are several
places where `npm.config.foo` is accessed blindly, resulting in these
kinds of errors and stack traces:
TypeError: Cannot read property 'get' of undefined
at errorMessage (.../lib/utils/error-message.js:38:39)
...
TypeError: Cannot read property 'loaded' of undefined
at exit (.../lib/utils/error-handler.js:97:27)
...
LBYL by checking `npm.config` first. Addresses a small part of #502.
