counsel-rg, counsel-ag don't work with tramp

[li1]

Issue

I am trying to run counsel-rg / counsel-ag on a remote server using TRAMP.

This doesn't work, as the remote binary apparently isn't being used for searching.

Steps to reproduce:

• Install rg / ag on remote server (at /usr/bin/rg / /usr/bin/ag)
• clean emacs init with ivy & counsel installed from melpa: (use-package counsel :ensure t :config (ivy-mode 1)) (ivy 0.12)
• C-x C-f to tramp into some remote file ssh://...
• M-x counsel-rg or M-x counsel-ag
• error message: "no such file or directory, rg" / "required program ag not found in your path"

Notes

• Commenting out the (counsel-require-program counsel-ag-command) suppresses the error message, but rg / ag remain dysfunctional
• installing ripgrep on the local machine also passes the file not found error, but obviously leads to other issues as the local binary is being used to search through remote buffers.

Update: I noticed that on long-running tramp sessions, rg and ag start to work. Perhaps the caching just takes a while. Also, at that point I receive an error code if I remove the remote binaries. So it appears that

1. The check for installed ag/rg is always looking at the local binary even if they should be executed remotely (not a big deal imo)
2. Initial caching takes a (pretty long) while — not sure what the reason for that might be

Thanks, please test.
