davidbaumwald aeb5d2ef17 Upgrade/Install: Fix parameter count in error call when an automatic core upgrade fails.
During automatic core upgrades, if installation results in a `WP_Error`, the `error` method is called on the skin with the details.  However, in this case, two parameters are passed to `$skin->error`, but only one is accepted.  This change passes only the running `WP_Error` instance as the sole parameter to `$skin->error`.

Also, this change adds an additional error to `$upgrade_result` before finally being passed to `$skin->error`, indicating that the installation failed.  This adds additional context to the failure.
