fix result returned empty result list by adding result to function call

[dan-gut1]

This is an in function call fix.
When ever '_recursive_get_connections' function is call a list should be passed with it, if list doesn't passed a new list will be initiated within the function (Line: 25)

Note: I'm unable to test this fix and encourage you to use the global list fix since i was able to check it on my environments.

Changes:

1. Line: 18 - Adding 'Result' to function call with default value None.
2. Line: 25 - Result list comprehension.
3. Line 35 - When recursive call takes place - now the call from within the function will pass current and updated list.
