[Regression][OSX][5.5] 'Couldn't decompress package' error is shown after importing package through Launcher

Steps to repro:

1. Open Unity;
2. In the Launcher window click 'New' button;
3. Click 'Add Asset Package' button;
4. Select 'Gaia - Terrain Creation Texturing population';
5. Click 'Done';
6. Enter the name of the project, specify path and click 'Create Project'.

Expected result:
Package starts to decompress, and is eventually imported to the 'Assets' folder of the project.

Actual result:
- Decompressing doesn't happen;
- Editor throws error : Failed to import package with error: Couldn't decompress package.

See attached video and actual.png screenshot.
Regression introduced in 5.5.0b6.

Workaround is to import the package when launching Asset Store from Editor.
