Fix default value in slices

[moycat]

The default values are applied before the config is loaded. So the later loaded structs in the slice don't have default values.

https://github.com/jinzhu/configor/blob/1095c485b440be00e1ddf075f4acdbebc3d6e97e/utils.go#L375-L391

Loading the default values after parsing config files and env should fix this.

Related to #67.

Well, at least no tests fail. You can add a unit test when you remember it.
