### Issue description

When assigning a lambda to a variable right after an if statement, the parser seems to understand that a ternary expression is happening when in fact it is not.

### Steps to reproduce

Put the code bellow on a script on an empty project
```gdscript
func test():
	var v
	if true: v = (func(): test())
	if true: v = (func(): test())
	if true: v = (func(): test())

	if true: v = func(): test()
	if true: v = func(): test()
```

### Minimal reproduction project

N/A
push_text("Assert ( ");
	print_expression(p_assert->condition);
	push_line(" )");
}
void GDScriptParser::TreePrinter::print_assignment(AssignmentNode *p_assignment) {
	switch (p_assignment->assignee->type) {
		case Node::IDENTIFIER:
			print_identifier(static_cast<IdentifierNode *>(p_assignment->assignee));
			break;
		case Node::SUBSCRIPT:
			print_subscript(static_cast<SubscriptNode *>(p_assignment->assignee));
			break;
		default:
			break; 
	}
	push_text(" ");
	switch (p_assignment->operation) {
		case AssignmentNode::OP_ADDITION:
			push_text("+");
			break;
		case AssignmentNode::OP_SUBTRACTION:
			push_text("-");
			break;
		case AssignmentNode::OP_MULTIPLICATION:
			push_text("*");
			break;
		case AssignmentNode::OP_DIVISION:
			push_text("/");
