Before this moment relationships managing page was using strings from
other context - from counters, but in order for translators to be able
to translate it relatively to the page, it must use separate strings.

I've split the strings for "Following" and "Followers" and put them to
"relationships" keyset in localization file. This should solve this
issue.

Fixes #10863

Rename "abandoned" to "moved", and "active" to "primary"
