waiting_for_cluster_members synchronous function should return state.remote instead of state.name [JIRA: RIAK-2270]

[travisbhartwell]

Specifically, this line:

https://github.com/basho/riak_repl/blob/develop/src/riak_core_cluster_conn.erl#L309

which is:

    {reply, {waiting_for_cluster_members, State#state.name}, waiting_for_cluster_members, State};

I believe it should be:

    {reply, {waiting_for_cluster_members, State#state.remote}, waiting_for_cluster_members, State};

If it were to follow the pattern of the reply from other states, like this:
https://github.com/basho/riak_repl/blob/develop/src/riak_core_cluster_conn.erl#L172
https://github.com/basho/riak_repl/blob/develop/src/riak_core_cluster_conn.erl#L227
https://github.com/basho/riak_repl/blob/develop/src/riak_core_cluster_conn.erl#L245

The error shows up when riak-repl displays the connections:
https://github.com/basho/riak_repl/blob/develop/src/riak_repl_console.erl#L303

The string_of_remote can't pattern match on just a string, it was expecting {cluster_by_addr, {IP, Host}} or {cluster_by_name, ClusterName}, which is the contents of state.remote.

I could do a PR with this change but it would be untested since I don't know how to make and test a build (new to Basho and working on Riak Explorer at the moment).
