title: Logic App - Cannot find (NotFound) queue with slashes in the name
body: <p>I am trying to have a Service Bus queue trigger my flow in Logic App.
  I have used service Bus queue trigger and passed the queue name that is 'test/test' - I am trying to have it work for queues with slashes in the name.
  It does not work, I receive the error type NotFound and the input data of the error reads:</p>
  
  <pre><code>...
      "method": "get",
      "path": "/test%2Ftest/messages/head",
      "queries": {
          "queueType": "Main"
      }
  ...
  </code></pre>
  
  <p>I have seen on the portal that / character is changed to ~ and tried to do this as well, both in the designer and in code, still no luck.</p>
  
  <pre><code>does not help
  "path": "/@{encodeURIComponent('test/test')}/messages/head",
  nor
  "path": "/test/test/messages/head",
  nor
  "path": "test/test/messages/head",
  nor
  "path": "/test~test/messages/head",
  nor
  "path": "/@{encodeURIComponent('test~test')}/messages/head",    
  </code></pre>
  
  <p>I can't influence the rest of the SB infrastructure and move to nicely named queues, it is just a place I wanted to hook into and suck the data out.
  Please help if you see a solution.</p>
  
  <p><strong>Edit</strong>:</p>
  
  <p>I think there is some inconsistency in working of the Designer and the logic behind it, because when I use a connection string with Manage policy, the Designed allows to browse the queues and pick one that is test/test.
  It gets configured by following the rules of the Designer but cannot be used (bug?). The tries in the Code view are just to find a workaround for the issue.</p>
