Infer symbol relationship for object literals property in return statement

[olafurpg]

Previously, scip-typescript didn't infer correct relationships between the object literel property and interface property in return statements like below:

interface Configuration {
  property: number
}

export function returnStatement(): Configuration {
  return {
    property: 42,
  }
}

This commit fixes this specific issue. This commit also adds a test case for a situation where scip-typescript doesn't infer the relationship today but tsserver does. We should fix that in the future.

Realized the previous logic failed as soon as you didn't have a toplevel return statement. I have a half-baked idea how to clean up the logic so that we pass down the inferred type while traversing the AST avoiding the need to look up parents (which is typically a sign of a broken abstraction IME).
