Seems like some registries/proxies could return all versions no matter which major prefix we're querying. It leads us to increment major and fetch them over and over.

It's confirmed that artifactory returns all versions in any major, so this is the fix

@zharinov please test on public goproxy too, to reduce chances of regression
