Dredd: Dredd fails to run openapi3 when square brackets are used for query parameters

[yourithielen]

Dredd fails to run when using an openapi3 file that uses square brackets in the query parameter names. Other issues regarding this problem seem to be closed/fixes but the problem still exists.

What's your dredd --version output?

dredd v9.0.4 (Linux 4.18.0-17-generic; x64)

I think the cause of this problem is because Dredd is running an older version of the OAS 3 parser and I believe once that's updated to fury-adapter-oas3-parser 0.7.4 this problem will go away. @honzajavorek mentioned to me that updating is blocked by some internal refactoring, I am not sure which issue is tracking that though.

So Dredd doesn't fail anymore on the original issue but now skips the tests that have square brackets in the query parameter name:
warn: API description URI template expansion warning in /api/spec.oai (API > /users > Get all the users > 200 > application/vnd.api+json): Ambiguous URI parameter in template: /users{?filter%5Bemail%5D}

Hmm, that sounds like what I described here https://github.com/apiaryio/dredd/issues/1256#issuecomment-468632610 but I thought that was fixed by https://github.com/apiaryio/dredd-transactions/pull/246
