Fix console logging and turn it on unconditionally if we're doing a debug build

Testing Done:
Ran `ninja reconfigure` with a debug buildtype (which is the default build type) with console-logging on and off and verified it was turned on. Also ran `ninja reconfigure` with a release buildtype and verified that the `console-logging` option was honored.
