saltutil.wheel minions.connected does not return anything with remote minions

[Ch3LL]

Description of Issue/Question

On the head of 2016.3 when testing the fix for issue #32446 there is no return for remote minions. I am expecting the following error: ERROR: This command can only be executed on a minion that is located on the master.

Setup

1. 2 minioins connected to a master. One of them local and one of them remote

Steps to Reproduce Issue

1. run the following: salt '*' saltutil.wheel minions.connected
2. And you will see that the remote minion does not return anything:

root@ip-10-95-162-59:~/salt# salt '*' saltutil.wheel minions.connected -lwarning
masterminion:
    - masterminion
    - remoteminion
remoteminion:

[rallytime]

After reviewing the changes in this code from 2015.8 to 2016.3, the remote minion no longer throws a SaltInvocationError when attempting to run wheel commands as it did in 2015.8. Instead of throwing the error, the remote minion returns as "empty".

For example, a saltutil.wheel minions.connected command returns an empty list. While this is a correct return, and is expected behavior for a remote minion - it wouldn't have any minions connected to it, it is not necessarily obvious of why this return is empty.

@Ch3LL and I spoke offline about this and agreed that the solution to this bug is better documentation, as submitted in #34214.
