A used private variable is reported as assigned but never used

[nightroman]

For the script like

$private:x = 42
$x

Invoke-ScriptAnalyzer reports

RuleName                            Severity     FileName   Line  Message

PSUseDeclaredVarsMoreThanAssigments Warning      test.ps1   1     The variable 'private:x' is assigned but never used.

This is not quite right because the variable is used in the next line after assignment.

Thanks for the report. This is fixed with #424
