FIX: improvements for vanilla bulk import (#10212)

Adjustments to the base:
1. PG connection doesn't require host - it was broken on import droplet
2. Drop `topic_reply_count` - it was removed here - https://github.com/discourse/discourse/blob/master/db/post_migrate/20200513185052_drop_topic_reply_count.rb
3. Error with `backtrace.join("\n")` -> `e.backtrace.join("\n")`
4. Correctly link the user and avatar to quote block

Adjustments to vanilla:
1. Top-level Vanilla categories are valid categories
2. Posts have `format` column which should be used to decide if the format is HTML or Markdown
3. Remove no UTF8 characters
4. Remove not supported HTML elements like `font` `span` `sub` `u`
