[Plugin: Simple Login Redirect] redirect does not work for multisite

Hi,
The redirect is not working when used in a multisite installation. This may be caused by the last update to wordpress, because this issue only manifested after the update.

The issue is the SQL query: $wpdb->prefix returns the multisite prefix which will be wp_#_ instead of wp_ if the current site is not the primary site. The problem is the usermeta table for multisites use the primary user table, so the prefix should wp_, not wp_#_.
I worked around this by using $wpdb->base_prefix instead, as suggested here:

As I said, this is probably only an issue for secondary sites on a multisite installation. I’m guessing it does not affect the primary site.

Otherwise, thanks for the useful plugin!
