PERF: limits use of redis cache while building emojis list (#19013)
We were doing get on Redis two times for each emoji while building the custom/standard/all lists which where resulting in ~3710 Redis calls. Given the emoji DB file is loaded in memory while we build/cache the emojis list this is unnecessary and slow.

As a simplification in pseudo code here is an explanation of what we were doing:

```ruby
emojis.each |emoji_name|
  aliases = get_aliases_from_redis_cache(emoji_name)
  is_tonable = get_is_tonable_from_redis_cache(emoji_name)
  build_emoji(emoji_name, aliases, is_tonable)
end
```

The two redis calls are now simplified to a simple hash access: `@db[emoji_name]`
