Update to a newer version of npmi to prevent node-uuid warning

[Ed Morley]

Hi!

gitbook-cli@2.3.2 has a strict dependency on npmi@1.0.1, which itself depends on npm@^2.1.12 (currently 2.15.12), which depends on request@~2.74.0, which still uses the deprecated node-uuid package.

Unfortunately this results in:

[1/4] Resolving packages...
warning node-uuid@1.4.8: Use uuid module instead

Please could gitbook-cli be updated to use a newer npmi, thereby preventing the noise from this warning? :-)

Been seeing this too.
