All arguments passed to the initial remote connection command were
initially blindly passed to `scp` or `sftp` command line.
This is an issue with some arguments like "-X" or "-Y" that either does
not exist, or have a different semantic.
This PR introduces a denylist of arguments before crafting the command
to execute.

Reproduce steps:

1. Create a new remote connection, e.g `ssh -X user@192.168.1.1`
2. Expect the upload of the remote server to fail with a message saying
that '-X' is not a valid argument for `ssh` / `sftp` depending on your
setup.
