Unable to Update API with Open API yaml File

[exalate-issue-sync]

Describe the bug :

An Open API yaml file can be used to import and create a new API, but it cannot be used to import and update an API.

To Reproduce :

Steps to reproduce the behaviour:

1. Import an Open API yaml file to create a new API, which should be successful
2. In the new API, click import again to update the API, and try to use the same yaml file.
3. The following error will appear: Cannot invoke "io.gravitee.definition.model.DefinitionVersion.equals(Object)" because "definitionVersion" is nul
4. For the same API, trying to update it using the same file but in a json format instead of a yaml is successful.

Expected behaviour :

The Open API yaml file should be able to create and update an API version as it was able to in previous versions.

Current behaviour :

An Open API yaml file cannot be imported to update an existing API.

Useful information :

ERROR i.g.r.a.m.r.provider.ThrowableMapper - Internal error java.lang.NullPointerException : Cannot invoke "io.gravitee.definition.model.DefinitionVersion.equals(Object)" because "definitionVersion" is null
