Fixed a few issues with packages installation/removal console

### What does it do ?

Instantiate a new "console window" on every action (install/reinstall/remove) instead of trying to load previously loaded one (if any).

### Why is it needed ?

If you perform multiple actions (install/removal...) without reloading the package manager page, only logs from the first action (ie. install) would be displayed (so, uninstall logs would not, but any subsequent package installation will display logs. works the other way around).
