Users of `:dalli_store` may have been passing an explicit `nil` parameter for the servers:
```ruby
config.cache_store = :dalli_cache, nil, { expires_in: 2.hour, compress: true }
```
If they simply changed `:dalli_cache` and `:mem_cache_store`, the existing code passes `addresses = [nil]` to Dalli (instead of `nil`), which cause exceptions when people try to access the cache:
```
> Rails.cache.fetch('foo')
NoMethodError: undefined method `match' for nil:NilClass
```
This change allows users to continue passing the explicit `nil`, making migrations from `:dalli_store` to `:mem_cache_store` simpler.
