spark hive metastore setting is ignored in 0.8.0 docker

[Alex Dzhagriev]

Hello,

I have set the "hive.metastore.uris" config value to use a remote metastore
in the spark interpreter, however the local megastore is used. That worked
fine on the previous version 0.7.3 and works if I uncheck the
"zeppelin.spark.useNew" setting.

Thanks, Alex.
