Forcing new version with meta-package doesn't uninstall cleanly

(Initially raised in https://github.com/chocolatey/cChoco/issues/91)

Given a machine that had successfully ran:

cChocoPackageInstaller node {
Name = "nodejs"
Version = "8.1.0"
DependsOn = @("[cChocoInstaller]Chocolatey")
}

Then if that is updated to

cChocoPackageInstaller node {
Name = "nodejs"
Version = "8.2.1"
DependsOn = @("[cChocoInstaller]Chocolatey")
}

Then the old version is uninstalled and it appears to fail to handle the nodejs/nodejs.install combination (it prompts whether to uinstall nodejs.install but immediately continues assuming no response).

Here is the relevant extract from chocolatey.log

Everything ends up ok eventually as when the new version is installed then that results with nodejs and nodejs.install both being at 8.2.1

Start by reproducing the cChocoPackageInstaller upgrade from nodejs 8.1.0 to 8.2.1 and review the corresponding chocolatey.log output. Trace the uninstall handling for the nodejs/nodejs.install metapackage combination; done means the old packages are handled cleanly without the timed-out prompt and the upgrade completes consistently.
