vim-patch:8.1.1349: if writing runs into conversion error backup file is deleted

Browse Source 
Problem:    If writing runs into a conversion error the backup file is
            deleted. (Arseny Nasokin)
Solution:   Don't delete the backup file is the file was overwritten and a
            conversion error occurred. (Christian Brabandt, closes vim/vim#4387)
