[TIMOB-11612] MobileWeb: console: js logging functions with no arg do not log to console at all

console functions with no args do not log to console at all. This does not occur with Ti.API calls, and does not occur on iOS or Android. This is a parity issue. If there is no arg, there should be a null string printed to console (with js line info for mobile web implementation). Steps to Reproduce: 1. Run code:

/* console */

console.log();
console.debug();
console.info();
console.warn();
console.error();

/* Ti.API */

Ti.API.trace();
Ti.API.debug();
Ti.API.info();
Ti.API.warn();
Ti.API.error();
Ti.API.log();

Actual Result:

[TRACE]  index.html:11221
[DEBUG]  index.html:11221
[INFO]  index.html:11221
[WARN]  index.html:11221
[ERROR]  index.html:11221
[LOG]  index.html:11221

Note: Only the Ti.API calls are printed. Expected Result: All calls should be printed (including js console object).
