Bugfix: Avoid choosing parent snapshots newer than time of new snapshot
Avoid choosing parent snapshot newer than time of current snapshot Currently, `restic backup` (if a `--parent` is not provided) will choose the most recent matching snapshot as the parent snapshot. This makes sense in the usual case, where we tag the snapshot-being-created with the current time. However, this doesn't make sense if the user has passed `--time` and is currently creating a snapshot older than the latest snapshot. Instead, choose the most recent snapshot which is not newer than the snapshot-being-created's timestamp, to avoid any time travel. Impetus for this change: I'm using restic for the first time! I have a number of existing BTRFS snapshots I am backing up via restic to serve as my initial set of backups. I initially `restic backup`'d the most recent snapshot to test, then started backing up each of the other snapshots. I noticed in `restic cat snapshot <id>` output that all the remaining snapshots have the most recent as the parent.

The `backup` command, when a `--parent` was not provided, previously chose the
most recent matching snapshot as the parent snapshot. However, this didn't make
sense when the user passed `--time` to create a new snapshot older than the most
recent snapshot.
