Wrong go to definition in match expression when matched value and the scrutinee are the same

[ironcev]

In the below example, when going to definition for both EXAMPLE_CONSTs in the match expression we should land on the definition of the constant. This is the case for the first EXAMPLE_CONST. However, when calling Go to Definition for the second instance, for the scrutinee, we land on the EXAMPLE_CONST above, the matched value in the match expression.

const EXAMPLE_CONST = 0;

...

match EXAMPLE_CONST {
    EXAMPLE_CONST => {}
    _ => {}
}

I've extended the go_to_definition_for_matches() test to demonstrate the issue. The extended test and fixture can be found in the branch ironcev/go-to-definition-issue-in-match-exp:
