swagger_1 -> swagger_2: Unrelated tags based on path are added

[bobvanderlinden]

When converting a swagger_1 spec to swagger_2, unrelated tags are being added in addition to the tags that are defined in the swagger_1 specification. I cannot find a way to disable this behaviour.

This is because of the following option:

This is a bit confusing, because tags from swagger_1 are already copied over:
