PSScriptAnalyzer incorrectly scopes variables in begin/process/end scriptblock

[kborowinski]

PSScriptAnalyzer incorrectly adds scope to begin/process/end scriptblocks when it should treat them as one scope:

[TimCurwick]

This also happens in the ForEach method:

$Script = @'
$A = @()
(1..2).ForEach{ $A += $_ }
$A
'@

Invoke-ScriptAnalyzer -ScriptDefinition $Script | Select -ExpandProperty Message

The variable 'A' is assigned but never used.

Bug still exists today and it is very annoying.
