Choco not removing old file until second run of installation.

What You Are Seeing?

Files in the C:\ProgramData\chocolatey\lib[xxx]\tools folder don't seem to get properly replaced until the second run of an installation. On the first installation of a new version of a package the contents of the nuget get unpacked into the lib\[xxx]\tools\ folder but the old files are still left over, when there are new files in the package.

What is Expected?

The content of C:\ProgramData\chocolatey\lib[xxx]\tools contains only the files in the latest version of the package.

How Did You Get This To Happen? (Steps to Reproduce)

Have two versions of a package available on your chocolatey server. The contents of the Tools folder on the server are e,g

In Package version 1.0:

.\chocolateyinstall.ps1 .\chocolateyuninstall.ps1 .\InstallFilesv_1.0.zip

In Package version 1.1:

.\chocolateyinstall.ps1 .\chocolateyuninstall.ps1 .\InstallFilesv_1.1.zip

Then: Choco Install version 1.0 of the package. (normal install) Choco upgrade to version 1.1 (lib[xxx]\tools\ will still contain files from the old install if above) Run choco upgrade to version 1.1 again. (lib[xxx]\tools contents will be properly erased)
