Fix: BUG#348 Parameter change detection fix when path doesn't change but PathParams AND Parameters are changed (But named the same)

[mishukdutta-toast]

• When endpoint pathParams change and Parameter names are changed to be similar to pathParams
  • Don't remove parameters from the path
  • This allows the ChangedParameter class to not lose parameters and detect/return changes

Fixes: #353

OperationsDiff.java:
removePathParameters(context.getParameters(), params);

removes Parameters which are marked - in: path

So changes to the schema for those parameters are not detected anymore when .getParametersDiff().diff(... is run after removal
