Extract is called before validate in http requests

**Citrus Version**
3.4.0

**Expected behavior**
Validate should be called first, otherwise the error message is confusing.

**Actual behavior**
extract is failing before validate is failing

**Test case sample**

First example: is failing because status code is wrong (error message is fine)
```
testRunner.run(http()
.client(myClient)
.send()
.post("/path"))
.message()
.header("Accept", "application/json")
.header("Content-Type", "application/json")
.body(new ClassPathResource("whatever.json")));
testRunner.run(http()
.client(myClient)
.receive()
.response(HttpStatus.OK)
.message()
.type(MessageType.JSON);
```

Second example is failing in extract method instead of validate
```
testRunner.run(http()
.client(myClient)
.send()
.post("/path"))
.message()
.header("Accept", "application/json")
.header("Content-Type", "application/json")
.body(new ClassPathResource("whatever.json")));
testRunner.run(http()
.client(myClient)
.receive()
.response(HttpStatus.OK)
.message()
.type(MessageType.JSON)
.extract(JsonPathSupport.jsonPath().expression("$.id", ${myId}"));
```
