Members list, paginate in even numbers

[sseerrggii]

With the new view of members, we continue paging every 25 members, but in desktop we see two cols, so will be better to paginate every 20 members.

@sseerrggii did you mean 20 on both sections /members and /members/manage? Or you prefer something like 20 on /members and 30 on /members/manage? I don't know... just asking, maybe under the manage section makes sense to display more records.

Mmmm 🤔

I don't find reasons for have more records on /members/manage , we can change both to 20.

@sseerrggii I pushed this change in this branch #416
