NPE printed out when loading client properties

Running tests, I get these stack traces:

Somehow, tests are still passing. I'm assinging @shinfan to this since I think Shin was working on property loading a few weeks ago. Could you help diagnose?

[shinfan]

Oh this is actually expected... the properties file maybe missing for some tests. I think I can modify the code to just ignore these exceptions (currently the stacktrace is printed))

Removed the release-blocking label.

Technically this isn't closed because there isn't a gax release pulled into google-cloud-java with the fix.

Thank you @shinfan for the explanation, so it's not blowing things up, just looks scary :)

[garrettjonesgoogle]

A newer gax has now been pulled in which includes the fix.
