Fix for building selenium project

In case the user is trying to build the entire project using `./go build`
or trying to build the standalone-server. The builds were failing with
the below exception :

BUILD FAILED: The rule //java/client/test/org/openqa/selenium/remote:common-tests
could not be found.

This was caused because the tasks in the Rakefile were still referring to
"common-tests" task instead of the new "small-tests"
