schema is not defined crash in v1.1.7

[schneivo77]

Hi,

an openapi definition which was converted with a warning in v1.1.6 now, in v1.1.7, fails and crashes the converter with the following error:

ReferenceError: schema is not defined
    at safeSchemaFaker (...\node_modules\openapi-to-postmanv2\lib\schemaUtils.js:170:65)

Here is the link to the line where it crashes in v1.1.7:

openapi-to-postman/lib/schemaUtils.js

Line 170 in 0a66b5f

'Error faking a schema. Not faking this schema. Schema:', schema,

I guess it's because the definition of schema object was removed in v.1.1.7 and it was missed to rename or remove the occurence it in the catch block...

Here is the link to the line where the schema object was removed in the commit to v1.1.7:
