[shlomisas]

Describe the bug
First of all, great initiative! thank you for that!

I installed the PWA via https://postwoman.io and then the download link doesn't appear anymore, i wanted to have it back (to take a screenshot and share it with my team) but after i uninstalled the app via chrome://apps the link doesn't appear there anymore, i tried to delete the web-worker, disabled the cache, use incognito but it's still not there.

To Reproduce
Steps to reproduce the behavior:

1. Install the PWA version via https://postwoman.io by clicking the link on the top header (next to the GitHub link)
2. Uninstall the app via chrome://apps
3. Go back to https://postwoman.io and looks for the same installation link
4. The link isn't there

Expected behavior
The link should be there and you'll be able to re-install the app

Once you install the PWA, "Install PWA" button will be hidden.
To restore the button:

1. Unintall the current PWA
2. Clear brower cookie and site data
3. Navigate to http://postwoman.io

I did that (as mentioned I tried Incognito mode as well) but it still not appears.

The app is uninstalled, cookies/localStorage is clean (or Incognito) but it's not there.

I just repeated the above steps and I was able to restore the PWA button.

Don't forget to clear cookies

Here you can see a video of it: https://www.screencast.com/t/AA2JmU69y (sorry for the SWF :( )

Cookies are cleared, and as you can see in the video, Incognito was in use as well.

Incognito mode won't allow apps to use localStorage which is essential to PW. Consider clearing cookies and site cache/data and reefresh.
