`PSUseDeclaredVarsMoreThanAssignments` and assigning multiple variables

[iRon7]

Aside from the false positive issues with the PSUseDeclaredVarsMoreThanAssignments rule, it has also a false negative bug:

This concerns assigning multiple variables:

This (as the only script line), correctly reports a PSUseDeclaredVarsMoreThanAssignments volitation on $a:

$a = $null

But this doesn't:

$a, $b = $null
