Fix parseNodeRecursive: Correctly recurse into TemplateLiteral expressions

Description

In the fuction parseNodeRecursive of lib/util/ast.js, the case for TemplateListeral nodes would always recurse over exp.right for all expressions in the template. However, these expressions are not necessarily binary expressions. Removing the .right will make sure that e.g. ConditionalExpressions are also checked.
