Title: Fix bug with finding nodes in index with spaces in value. 

Setup:
```ruby
new_node = @neo.create_node
key = "someKey"
value = "some value" # this has a space
@neo.add_node_to_index("indexName", key, value, new_node)
```

Before fix:
```ruby
found_node = @neo.find_node_index("indexName", key, value)
# => nil
```

After fix:
```ruby
found_node = @neo.find_node_index("indexName", key, value)
# => [{ .. a whole lot of JSON .. }]
```
