Change: Backups from stdin no longer have a parent

Snapshots made with `restic backup --stdin` no longer have a parent snapshot.
Since parent snapshots are only used to skip files in the scanning phase
based on filename and timestamps, the parent snapshot of a `--stdin` snapshot
was meaningless to begin with. Not setting a parent allows `restic backup`
to skip some startup operations.

The `--parent` option is still available for `restic backup --stdin`,
but is now ignored.

Don't set a parent for --stdin backups Loading any parent tree for these only wastes time and memory. Fixes #3641, where it was shown that the most recent tree will get picked. --parent is now implicitly ignored when --stdin is given. 2022-02-06 16:43:22 +00:00			`Change: Backups from stdin no longer have a parent`
