Fix test broken

test broken

There was lua script loading problem with PrefixedRedis.

This is re-produce code.

from stdnet.backends import getdb

backend = getdb('redis://127.0.0.1:6379?db=1')

prefixed_client = backend.client.prefixed('foo')
# hide the problem when un-comment this.
#print backend.client.execute_script('keyinfo', (), '*')
print prefixed_client.execute_script('keyinfo', (), '*')

tox

python-stdnet supports multi python platform. so tests should also be run in them.
