MalformedURLException: unknown protocol: smb when migrating services from EI to MI 1.2.0

[JanakaPushpakumara]

Description

The following Error exception can be observed when we migrate inbound EP and the inject sequence which contains the file connector configuration with smb endpoint URL.
Ex:

Steps to Reproduce

1. Copy the carbon application with the file connector 3.0.6 car.zip
2. Deply the inbound EP and inject a sequence

3. Copy a sample file into the consumer location and connector source location
   echo "abcdabcdabcd" > abc.txt ; cp abc.txt ../temp;
