Fixes #920.
There were actually two problems.
One mentioned in the issue, merging values into arrays. That is fixed using array_replace_recursive instead of array_merge_recursive.
Second was caused by the array_filter and trying to set number_of_replicas to 0. Array filter converts the value to boolean FALSE and removes it from the array. I added a custom callback function to compare it using identical operator.
