Settings param cannot be set to $_ inside of a foreach-object loop

When the value of the -Settings parameter is set to $_ inside of a foreach-object loop, PSScriptAnalyzer is unable to find the settings file.

Steps to reproduce:
Create a file that violates a rule that is only checked if a particular setting is triggered.
IE:

if ($true)
{
    Write-Output 'Something'
}

This code will throw errors if -Settings is set to CodeFormattingStroustrup but not if -Settings it is omitted.

The following command returns warnings.
invoke-scriptanalyzer -path C:\files\ax.ps1 -Settings 'CodeFormattingStroustrup'
But this one does not.
'CodeFormattingStroustrup' | % { invoke-scriptanalyzer -path C:\files\ax.ps1 -Settings $_ }

Using -Verbose on the non-working example shows that PSScriptAnalyzer cannot find a settings file.

This occurs on version 1.15.0 of PSScriptAnalyzer.

Screenshot

從 Invoke-ScriptAnalyzer 入口點開始，使用 -Verbose 重現直接的 -Settings 值與 foreach-object 形式之間的差異。追蹤兩次呼叫中設定值的解析方式；完成標準是，透過管線傳入的 $_ 形式能夠定位 CodeFormattingStroustrup，並回報與直接命令相同的警告。
