[Bug] `:DiffviewOpen origin/main...HEAD` isn't working

[carlos-algms]

Description

The command to compare a remote branch with the current HEAD isn't working and throws an Error.

Expected behavior

It should work and show the diff panel comparing the remote with the local changes

Actual behavior

It opens the diff panel empty and shows the error: InvalidArgument :: Can't diff LOCAL against LOCAL!

Steps to reproduce

run: :DiffviewOpen origin/main...HEAD or: :DiffviewOpen origin/HEAD...HEAD
