PowerShellReferenceResolveProcessor should navigate to closest declaration

[ForNeVeR]

See this comment in PowerShellReferenceResolveProcessor: https://github.com/ant-druha/intellij-powershell/blob/baccc65fb41e834e8eb66642911f1a1259926856/src/main/kotlin/com/intellij/plugin/powershell/ide/resolve/PowerShellResolver.kt#L41

Also, look for the number of this issue in the project code base.

Let's investigate what this comment means and what's the current behavior of the resolve processor navigation. Is it really missing anything? I'm not currently sure about the contract of this component, but we have to figure it out.
