tapipy can't import with latest version of openapi-spec-validator

[georgiastuart]

tapipy appears to have broken with the 0.5.0 release of openapi-spec-validator, which is a valid version from the pip requirements. The resulting error is:

Traceback (most recent call last):

Manually downgrading openapi-spec-validator to 0.4.0 works just fine. This error occurs on the line
