fix: filter ssh commands where dest is not over ssh (#58)

This is one possible solution for the issue I'm facing where some commands:
 - check for `backup marker`
 - check that `dest` folder exists
 - creating the `latest` symlink

were actually running on the `src` instead of the `dest`.

Run `verbose` and you would note that some commands are now run locally

Args are: `--verbose [email protected]:/home/josh/Documents /tmp/edesk.local/Documents `

Snipped output shows where some commands which used to be run `remote` are now run locally

```
rsync-time-machine.py: Running remote command: test -e '/home/josh/Documents'
rsync-time-machine.py: Running local command: find '/tmp/edesk.local/Documents/backup.marker'
rsync-time-machine.py: Command output: /tmp/edesk.local/Documents/backup.marker
rsync-time-machine.py: Running local command: find '/tmp/edesk.local/Documents/' -maxdepth 1 -
rsync-time-machine.py: Running remote command: find '/tmp/edesk.local/Documents/backup.inprogress'
...
rsync-time-machine.py: Running local command: rm -f -- '/tmp/edesk.local/Documents/latest'
rsync-time-machine.py: Running local command: ln -s -- '2024-03-25-172323' '/tmp/edesk.local/Documents/latest'
rsync-time-machine.py: Running remote command: rm -f -- '/tmp/edesk.local/Documents/backup.inprogress'
```

* Add space to SSH command to fix error when using -i option

Using the `-i` option to supply a SSH key fails with the error 'Safety check failed - the destination does not appear to be a backup folder or drive (marker file not found).' This seems to be because of a missing space in the SSH parsing code which means that the key address and the SSH address get munged together. This pull request simply adds a space between them.

* add space elsewhere to make test pass
