remove verbose query params from path, like: {?paramA,paramB}

[Bancalets]

Spring swagger2 exported path values create entries like this one:

"/activity/{user}{?from,to}"

The result is a non importable json entry for Postman, as the Query Params (optional or not) are set twice, the second time with the right format, following the previous example:

"url": "{{scheme}}://{{host}}:{{port}}/service/activity/:user:?from,to?from={{from}}&to={{to}}",

The fix prevents this malformed entry and transforms it to:
"url": "{{scheme}}://{{host}}:{{port}}/service/activity/:user?from={{from}}&to={{to}}",

What is a valid entry and works fine with Postman JSON Import
