package.json needs update to pull the right version of google-gax@0.13.2

[merla18]

you will get:
the ERROR: TypeError: Cannot read property 'config' of undefined"
with any NL samples if you use google-gax@0.13.1. The latest version of the google-cloud-node/language package 0.10.3 is correct and pull google-gax@0.13.2
The package.json needs to be updated to have:
"@google-cloud/language": "0.10.3"
