Multiple file extensions while changing virtual disk type

[psadowski]

While creating a virtual disk, changing the hard disk file type adds a new extension to the file. It does NOT change the existing extension, just adds a new one. So, you may end up with something like "harddisk.vdi.vhd.vmdk.vdi.vhd.vmdk.hdd.qcow" if changed the type multiple times.

Not really a bug, just an anoing gui behaviour.

Ubuntu 20.04, Budgie Desktop, fresh install of VitualBox 6.1.8.
