Choco reports install location of last installed package, not the one its installing

### What You Are Seeing?
If you install a package (or upgrade, in my case), and at the same time something else is also upgrading, `choco.exe` will give the _other_ program's install location as the install location of the package it was installing.

In this screenshot, I am upgrading `buffalo`, and at the same time I did a vscode update (which finished first), and then I get this:


### What is Expected?

I expected it to show the correct installation path.

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

Install something externally while choco is instaling / upgrading.

### Output Log

Next time, I'll run with `--debug` and report back.

Start by reproducing the concurrent package installation or upgrade described in the issue, using --debug --verbose to capture the relevant output. Trace how choco.exe determines and reports the installation location for each package; done means the reported path belongs to the package currently being installed, even when another update finishes first.
