 We had a user on a multisite network try to activate their account and the
 only error message you get it "Could not create user". This is not
 helpful. We had to go digging through core to figure out why.

 Right now it uses wpmu_create_user() which returns false if
 wp_create_user() returns an error, instead of returning the error message
 from wp_create_user(). An easy improvement would be for wpmu_create_user()
 to return this error message instead.

 I've created a patch for a starting point. Will involve discussion over
 how much we want to update messaging for other interactions that use
 wpmu_create_user().
