Package loading is not saved if packager window is closed

# Description
If you open npm package ui, click install, do not wait until the package is installed and close npm packager ui and open it again - you will not see loading. In this case used can be confused and can install a package again while installation is already going

# Expected Behavior
State of loading to be saved even if npm packager ui is closed

# Actual Behavior
State of loading is not saved if npm packager ui is closed

# How to reproduce
1. Open npm packager ui
2. Click on install for some big package (if you install small package it will be installed immediately and you will not be able to reproduce)
3. See loading
4. Close npm packager ui
5. Open npm packager ui
6. Do not see loading

Start in the npm packager UI and reproduce the issue by installing a large package, closing the UI while loading, and reopening it. Trace how the loading state is handled across closing and reopening; done means the package still shows as loading and cannot be installed again while installation is in progress.
