Subject: [PATCH] Expand attribute output. #493 (#1277)

* Expand attribute output. #493

If attribute is actually an Object, expand it in the format `topic/key-subkey` in order to keep the same amount of topic levels for predictable parsing.
This only expands the first level of contained object. If more expansion are needed a more robust method should be implemented rather than just nesting `if`s.

* Fixing whitespace

fixing https://travis-ci.org/Koenkk/zigbee2mqtt/builds/507616980

* first time splitting line... obviously

Not sure what the proper approach is, but I guess we can put all params on new line.

* identation... really...

How is that `eslint`? any other requests?
