Comment (by obenland):

 We could check if `$updater->skin->result` is a `WP_Error` and set
 `$result` to that, but that wouldn't fix the underlying problem of
 `WP_Upgrader::install_package()` not setting its `$results` property
 correctly in some instances where errors occur. Like when the destination
 directory already exists.
