Hi,

So I'm experimenting with the OpenApiParser to quickly generate a mock for our API. I'm not very familiar with this software, so it may be an issue with my understanding. The issue is that the patterns that are generated for the paths seem to be incorrect. We have a path like:

paths:
  '/customers/{customerId}':
    post:

And the generated path match is this: ^//customers/example-value$. The problem is the presence of two forward slashes at the beginning of the route. I think the issue occurs in this line here:

https://github.com/WireMock-Net/WireMock.Net/blob/db158bcc7eb8195c5ae13665c67286865827275b/src/WireMock.Net.OpenApiParser/Mappers/OpenApiPathsMapper.cs#L106

The call to MapBasePath(servers) produces "/" and the call to MapPathWithParameters(path, parameters) produces "/customers/example-value". I think I understand that we are trying to prefix our routes with any path segment(s) that are on the server base path. However, the logic doesn't seem to account for the absence of any path segments (as my servers do not have any paths or trailing slash).

Maybe the combining of these strings needs to be more sophisticated to account for this scenario?
