AzureRM.* modules held in use by PSSA when Cluster 0.0.0.1 is scanned, prevents uninstall

Repro steps

Install-Module -Name Cluster -RequiredVersion 0.0.0.1 -Repository PSGallery
# This depends on AzureRM, which in turn depends on 45 AzureRM.* modules.  
# All get downloaded at install.

Invoke-ScriptAnalyzer -Path [PathToCluster] -Recurse -Severity Error

Invoke-ScriptAnalyzer -Path [PathToCluster] -Recurse -CustomerRulePath [someCustomRulesPath]

Uninstall-Module -Name Cluster -RequiredVersion 0.0.0.1
# Succeeds

Uninstall-Module -Name AzureRM.Websites
# One of the dependencies installed.
# Fails to uninstall, says is currently in use.

Expected Behavior

I should be able to uninstall the AzureRM.* modules. I don't expect PSSA to hold on to them.

We are unable to uninstall any of the AzureRM.* modules because something in PSSA is holding on to them. This appears to only happen for the Cluster 0.0.0.1 module.

使用 Cluster 0.0.0.1 重现列出的 Install-Module、Invoke-ScriptAnalyzer 和 Uninstall-Module 命令，对比有无 CustomerRulePath 时的扫描结果。跟踪 PSScriptAnalyzer 在这些扫描期间如何加载模块，并验证之后可以卸载 AzureRM.* 模块；当报告的锁定不再发生时即表示完成。
