patterns for follow_api for 5mln blocks

Andrzej Lisakrequested to merge
follow_api_patterns into master

Patterns created from hive-3 (0.23 HiveMind replayed to 5mln). Some tests modified to give nonempty response.

Reblogging functionality was apparently introduced shortly after 5mln block, so there can be no nonempty pattern for get_reblogged_by.
