[Bug Report] SoapUI 5.7.0 Import from swagger yaml fails because of $ref in parameter definition

Hello,

we have a swagger definition file in yaml and we are using $ref for parameter definition because the same parameter is used in multiple (many) endpoints.

But when import gets to this part of the code it fails and I receive error: 

java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because the return value of "io.swagger.models.parameters.Parameter.getIn()" is null

I looks like the import can not expand the $ref in to the parameter definition written behind the reference.

I tried the same yaml in ReadyAPI and it is working correctly.

Is there a solution for this, please?

Here I put the part of the code where it fails. In swagger editor this is a valid code without any errors.
