rhbz1124630 - need to override accept header for some clients to work

Very strange. I needed to add accept header to these two resource clients to make it work.
Otherwise the Accept header will be set to "text/html, image/gif, image/jpeg, *" and on the server it will cause an exception at org/jboss/resteasy/plugins/delegates/MediaTypeHeaderDelegate.java:42 which in result returns a 415 unsupported media type. 

I don't need to do this for other clients. I am very confused but this change fixed it.
It's not the Consume part. It's the client sending a Accept header and the server can't deal with it. I don't know how and why there is this header added (maybe by default?). Noticed the value is "text/html, image/gif, image/jpeg, *" which RESTEasy will try to break it down into two parts by /. It will turn out to be 4 and an exception will be thrown.

In these two clients, we don't really look at what comes back (it's a PUT and no payload in response) that's why I put wildcard for accept.
