Fix 2 bugs. Deleting file without yaml file and multi-word delete

The first bug output an error if trying to stage the deletion of the
yaml file if the file never existed. The error is now piped to /dev/null
and `|| true` is appended to the line which causes the script to carry
on execution

The second change is when deleting a file, you no longer have to quote
the file name if it is a multi word file. This puts it in line with the
new command
