"Install & Edit" button for Assetlib breaks ability to download multiple demos at once.

[ghost]

I tried my best searching for duplicates.

Godot version:

3.0.3

OS/device including version:

Manjaro x86_64

Issue description:

Clicking "Install & Edit" (the only choice besides cancel) closes the Project Manager and discards downloaded (but not installed) demos.

Steps to reproduce:
Download multiple demos from Assetlib and try to install the second one.

i.e. only one of these can be installed:

I just downloaded 5 demos that I wanted to look at one after the other and then found out about this bug. As a temporary solution however, the assets are downloaded to %TEMP%\Godot in Windows, so I just copied the zip files and extracted them to my project folder, then ran "Scan" from the Project Manager. This also had the nice benefit of me not having to create a name for each folder, but instead getting the original folder name from the zip file.
