Subject: [PATCH] Fix warning about block and default value

Ruby's Array#fetch accepts either a default value or a block, but not
both. If both are passed in, then it uses the block and outputs this
warning:

```
lib/liquid/static_registers.rb:34: warning: block supersedes default value argument
```
