Nested key value not returning if environment is not specified

[bmarotta]

If using environments, a nested key value won't return if not defined for the specified environment.

Example

{
"myData": { "myValue": "value" },
"development": { "myData": { "myValue": "otherValue" } }
}

The above example will return correctly "myData.myValue" if the environment is "development", but will return null if the environment is production.

The problem is a missing else for the if statement on line 272
if (this.environmentExists())
