Common: Get rid of a compilation warning.

debugLogEarly was replaced to an empty space and arguments of the function
became operators, grouped together by ():
Configuration.cpp: In member function 'bool ConfigurationTable::defines(const string&)':
Configuration.cpp:272:28: warning: left operand of comma operator has no effect [-Wunused-value]
   debugLogEarly(LOG_ALERT, "configuration parameter %s not found", key.c_str());
                            ^

This fix removes debugLogEarly together with its arguments.
