[BUG] spaces in schema.title causes spaces in interface

Created by: snebjorn

Description

When a response title is set and have spaces then the resulting model will also have spaces. Which is not allowed.

export interface Collection of Foo { 
    value?: Array<NAMESPACEFoo>;
}

The definition for schema.title

are taken directly from the JSON Schema definition and follow the same specifications

which is

4.5. Root schema and subschemas

The root schema is the schema that comprises the entire JSON document in question.

Some keywords take schemas themselves, allowing JSON Schemas to be nested:

{
    "title": "root",
    "items": {
        "title": "array item"
    }
}

In this example document, the schema titled "array item" is a subschema, and the schema titled "root" is the root schema.

So spaces in title is valid.

openapi-generator version

"@openapitools/openapi-generator-cli": "^1.0.1-4.1.3"... yes the version is 1.0.1-4.1.3 it's not a range - it's a bit weird. Check https://www.npmjs.com/package/@openapitools/openapi-generator-cli
