bcdb: fail to load schema when zdb is in user mode

[zaibon]

j.clients.zdb/zrobot.toml

addr = 'localhost'
adminsecret_ = ''
encryptionkey_ = ''
mode = 'user'
port = '9900'
secrets_ = '

j.servers.zdb/zrobot.toml

addr = '127.0.0.1'
adminsecret_ = ''
mode = 'user'
path = '/opt/var/zdb/zrobot'
port = 9900
verbose = true

Then trying to load bcdb:

In [1]: cl = j.clients.zdb.get('zrobot')
In [2]: db = j.data.bcdb.get(cl)
In [3]: db.tables_get('/opt/code/github/zero-os/0-robot/zerorobot/storage/')
