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:

Hi Paul,

Thanks for finding and fixing this bug!
Changes look good to me.

However, I can't seem to reproduce your error when removing L192-L193. When I remove these all tests still work. Could you elaborate on what seems to go wrong in this case?
