CBQE-5999: [16/n] CBQE-6046: Expect disable_ft_alias=True when disabl…

…e-ft-indexes=True

When you configure an archive, if you've disabled backing up fts-indexes
cbbackupmgr implicitly disables backing up aliases.

https://github.com/couchbase/backup/blob/mad-hatter/cmd/cbbackupmgr/config.go#L124

Consequently, we need to expect disable_ft_alias=True in the
backup-meta.json if disable-ft-indexes=True in the the backup-meta.json
verification.
