[bugfix] Fix Swagger spec and add test script (#2698)
* Add Swagger spec test script * Fix Swagger spec errors not related to statuses with polls * Add API tests that post a status with a poll * Fix creating a status with a poll from form params * Fix Swagger spec errors related to statuses with polls (this is the last error) * Fix Swagger spec warnings not related to unused definitions * Suppress a duplicate list update params definition that was somehow causing wrong param names * Add Swagger test to CI - updates Drone config - vendorizes go-swagger - fixes a file extension issue that caused the test script to generate JSON instead of YAML with the vendorized version * Put `Sample: ` on its own line everywhere * Remove unused id param from emojiCategoriesGet * Add 5 more pairs of profile fields to account update API Swagger * Remove Swagger prefix from dummy fields It makes the generated code look weird * Manually annotate params for statusCreate operation * Fix all remaining Swagger spec warnings - Change some models into operation parameters - Ignore models that already correspond to manually documented operation parameters but can't be trivially changed (those with file fields) * Documented that creating a status with scheduled_at isn't implemented yet * sign drone.yml * Fix filter API Swagger errors * fixup! Fix filter API Swagger errors --------- Co-authored-by: tobi <tobi.smethurst@protonmail.com>
