remember the refreshed lock file even if removal failed

Browse source 
This ensures that restic won't create lots of new lock files without
deleting them later on.

In some cases a Delete operation on a backend can return a "File does
not exist" error even though the Delete operation succeeded. This can
for example be caused by request retries. This caused restic to forget
about the new lock file and continue trying to remove the old (already
deleted) lock file.
