Imports fail in 14.5.2 fail with HTTParty::UnsupportedURIScheme error

Summary

Smart client validation in !70165 (merged) breaks imports from minimalist Git servers

Steps to reproduce

• Pick a gitdaemon publishing repositories via git:// protocol (NOT HTTP)
• Import a published repository via API

What is the current bug behavior?

• Import via Web GUI: Works, but HTTParty::UnsupportedURIScheme: 'git://<GIT_SERVER_URL>/info/refs?service=git-upload-pack' Must be HTTP, HTTPS or Generic error thrown in the logs
• via ReST API: Will fail immediately with HTTParty::UnsupportedURIScheme: 'git://<GIT_SERVER_URL>/info/refs?service=git-upload-pack' Must be HTTP, HTTPS or Generic error

What is the expected correct behavior?

• Import should work via API with git URL
