Stop vault creation when a vault's metadata cannot be read (closes #140)

GetNextDerivationIndex passed over a vault whose vault-metadata.json could
not be read or parsed, so the next vault made from the same mnemonic could
get that vault's derivation index and so the same long-term key. It now
returns an error naming the file, so vault create, vault import and init
stop with that error and leave the state directory as it was. A vault
directory with no metadata file is still skipped.

The regression test breaks one vault's metadata, once with content that
does not parse and once with a test filesystem that fails to open it, and
requires CreateVault with the same mnemonic to fail, naming the file, and
leave no new vault.
