Summary

This PR resolves issue added by ff9224e4adbfc1aee8503a2104276173a6b77d94 commit:

1. followRemote generated on base of "guest" layout that have no own "content" block, so we change to src/ostatus.js finished up with vue error about missed #content block
2. I failed to found a way how script('social', 'social'); from templates/main.php should load OStatus.vue, so I simply makes templates/ostatus.php based pn main.php

Suggested change fixes page https://cloud.mndet.net/apps/social/api/v1/ostatus/followRemote/mnd that loaded when you press "Follow" button at https://cloud.mndet.net/apps/social/@mnd/
