[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
