PkgDev.tag fails if the registry is not a fork but owned by the user.

[lassepe]

I would like to use PkgDev.tag in combination with my personal registry setup using LocalRegistry.jl. However, I'm running into this error message:

PkgDev.jl/src/tag.jl

Line 101 in 278dd85

fork_index===nothing && error("You need to have a fork of the registry in your github account.")

The reason seems to be that I am the owner of the registry repo. Thus, I don't have a fork of it. In fact, the gh_forks in the line above is empty.
