Http message sent instead of soap message if soap action send called with uri instead of autowired soap client

**Citrus Version**
v2.7.8

**Expected behavior**
Soap message should be sent

**Actual behavior**
http message sent

**Test case sample**
> Please, share the test case (as small as possible) which shows the issue

Actual behavior for
```java
soap(action -> action.client("http://localhost:8080/services/WS")
.send()
.soapAction("getTodoList")
.payload("\r\n" +
""));
```

Debug log:
```
08:57:40,387 DEBUG port.LoggingReporter| TEST STEP 2: send
08:57:40,422 DEBUG faultEndpointFactory| Found cached endpoint for uri 'http://localhost:8080/services/WS'

08:57:40,652 DEBUG client.HttpClient| Sending HTTP message to: 'http://localhost:8080/services/WS'
```

Actual behavior for passing client:
```java
@Autowired
private WebServiceClient todoSoapClient;

soap(action -> action.client(todoSoapClient)
.send()
.soapAction("getTodoList")
.payload("\r\n" +
""));
```

Start by reproducing the two Java SOAP action samples in the issue, comparing the URI-based client with the autowired WebServiceClient and their debug logs. Trace how the URI is resolved and selected for sending; done means the URI form sends a SOAP message rather than an HTTP message while preserving the soapAction and payload.
