Description:
$subject and it create a new folder instead.

Steps to reproduce:

1. Create the following API in the Integration Studio.

<?xml version="1.0" encoding="UTF-8"?>
<api context="/file" name="File" xmlns="http://ws.apache.org/ns/synapse">
<resource methods="POST" uri-template="/move">
        <inSequence>
            <property expression="json-eval($.source)" name="source" scope="default" type="STRING"/>
            <property expression="json-eval($.destination)" name="destination" scope="default" type="STRING"/>
            <fileconnector.move>
                <source>{$ctx:source}</source>
                <destination>{$ctx:destination}</destination>
            </fileconnector.move>
            <respond/>
        </inSequence>
        <outSequence/>
        <faultSequence/>
    </resource>
</api>

2. Invoke the API with the following payload. Make sure the destination folder is not an existing folder.

{
	"source":"/Users/IsuruUyanage/Music/integration-tests",
	"destination":"/Users/invalidFolderName"
}

Expected: It should provide an error message.
Actual: It returns a success response and create a new folder with the incorrect name.
