Use refer-clojure when overriding clojure.core fn names

[echeran]

I'm getting warnings and a NullPointerExceptions during lein compile, when I include a require statement for the namespace googlecloud.bigquery.tables.

Based on this SO answer, my hunch is that it is related to having a fn that shares the same name as a fn in clojure.core.

If that indeed is the problem, then solution would be to put a (:refer-clojure :exclude [list get]) inside the ns form. There are a few other namespaces in googlecloud.bigquery.* that might need that same fix.

The warning looks like

WARNING: list already refers to: #'clojure.core/list in namespace: googlecloud.bigquery.tables, being replaced by: #'googlecloud.bigquery.tables/list

and the errorlooks like

+1 on adding (:refer-clojure :exclude [list get])
