github handler fails to open issue when using gx inside a vim-fugitive git log output

[reegnz]

To reproduce:

• Use https://github.com/tpope/vim-fugitive
• Go to a git repo with a remote configured
• open neovim
• :G log
• look for a git commit message with a github issue link and move the cursor on top
• hit gx

Expected:

• issue opens in browser

Actual: I get prompted with the following message:

gx.nvim: No remote git repository found!

And then the plugin continues to open a google search with the text.

I think I've identified the issue: https://github.com/chrishrb/gx.nvim/blob/ea543829d7eb36c9bf80e43d7a27bd326bb8d3ed/lua/gx/git.lua#L23

With vim-fugitive's :G log this is a temporary file.

Nonetheless the handler should still work within a vim fugitive temp buffer displaying a git log.

I Propose that the plugin should fall back to the current working directory for path if it fails to discover a git remote on the current path.
