// TestListFailsWhenCurrentVaultDoesNotExist is a regression test for
// https://git.eeqj.de/sneak/secret/issues/156, where a currentvault file
// that was empty, held an invalid vault name, or named a vault that does
// not exist, made `secret list` report an empty vault. Listing must fail
// with an error that names the file and says to run `secret vault select`,
// `secret vault list` must still list the vaults, and selecting a vault
// must make listing work again. The name "." would make vaults.d itself the
// vault, and "../vaults.d/work" would reach the vault work by a path.
