Fix empty pickle file by adding missing optional log_config argument

[brussee]

Added the optional log_config argument to Builder. This fixes the otherwise empty pickle file produced by BaseNetQASMConnection on L409.

Also thanks to Ravi for helping to track this bug down.

FYI:
Removing L192 & L193 from BaseNetQASMConnection, because they are also present in Builder L248 & L249, results in the following error while running the tests:
