This commit makes sure to exclude the first solution when checking for an existing solution and has better tests -- the existing test does not accept the post prior to making the check.
There exists a bug in the following trigger (see screenshot) where if the user has an existing solution already, they will still pass validation for "first accepted solution" due to the trust level being "any".
There are three locations where a user's solution query is defined
- user summary
- user card
- user directory
This PR updates the queries to use data from the new `SolvedTopics` table instead of the `UserActions` table. And adds testssssss
As part of https://github.com/discourse/discourse-solved/pull/342, some discrepancies in the old implementation resulted in solved topics linking to posts that do not exist (dangling custom field value). Causing us to see the following when there are no `answer_post`
```
NoMethodError (undefined method `user' for nil)
```
This PR prevents the error.
This commit autoloads plugin files, and also extracts features into their own modules.
- `plugin.rb` is smaller
- external plugins like discourse-automation and discourse-assign have their own entrypoints
- solved filters as well
