Bundles are not being posted to the base API path

[RadovanTomik]

Description

Trying to post a Bundle Resource of type "transaction" results in it being posted to BASE_API/Bundle therefore resources that are part of the bundle are not created.

How to reproduce

Create a Bundle resource of type 'transaction' and resource_type 'Bundle'. Try to post it to a FHIR server using bundle.create(server)

What happens

The bundle can be found at BASE_API/Bundle and the resources in it have not been created on the FHIR server

What should happen

The bundle should be posted to just BASE_API and the resources in bundle.entries should be created/updated.
