Title: Updating a plugin deactivates it

Tested on the latest and greatest version (I JUST pulled 2 min ago).

1. Have an out of date plugin that is active.
2. Run 'wp plugin update pluginname'
3. Now you have an updated plugin that is IN active

That doesn't seem right. Shouldn't the plugin check if it's active and retain that state?
