Warning in server log: Attempt to read property "user_nicename" on bool

[WiredUK]

We are seeing warnings in our server logs:

[proxy_fcgi:error] [pid 711673] [client www.xxx.yyy.zzz:nnnnn] AH01071: Got error 'PHP message: PHP Warning: Attempt to read property "user_nicename" on bool in /home/site/public_html/wp-content/plugins/co-authors-plus/co-authors-plus.php on line 1124'

Since get_userdata can return false, I think it's worth putting a check in there.

Are you able to replicate this with the develop branch?

I have noticed this issue when calling count_user_posts on a guest author.
