Be more liberal in detecting NOSCRIPT error

Our redis client (with sentinel) is sending err.message as:
`Error: NOSCRIPT No matching script. Please use EVAL.`
Causing the NOSCRIPT detection to fail.

This was with the following installed:

```
$ npm ls | grep redis
├─┬ hiredis@0.1.16
│ │ ├── redis@0.7.3
├── redis-evalsha@1.1.0

```
