    [Dap] Fix not transcoding some files when we should
    
    When a source file to be transferred to a DAP did not match any
    available profile, it was not transcoded due to the fact that the
    extension returned was null and many in AcceptableMimeTypes for a
    device suffered the same. In that case null == null and no transcoding
    was performed.
