[TIMOB-11618] Android: Ti.API.log: function calls with one arg (log level) do not print as the correct log level, and have some format problems

Ti.API.log console logging calls with one arg (log level) do not print as the correct log level. They all default to [INFO] instead. This does not occur in MobileWeb. This is a parity issue. This is also an inconsistency within the Android platform because log calls with two args work as expected. Notice the two edge-cases as well with Ti.API.log() with no arg printing as [undefined] when it would normally be expected to be the null string, and Ti.API.log('log') with a freeform log type does not contain brackets when it normally would (see expected results for both). Steps to Reproduce: 1. Run code:

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

Actual Result:

[INFO][TiAPI   (  327)] [undefined] 
[INFO][TiAPI   (  327)] trace
[INFO][TiAPI   (  327)] debug
[INFO][TiAPI   (  327)] info
[INFO][TiAPI   (  327)] warn
[INFO][TiAPI   (  327)] error
[INFO][TiAPI   (  327)] log

Expected Result:

[INFO][TiAPI   (  327)]
[TRACE][TiAPI   (  327)] trace
[DEBUG][TiAPI   (  327)] debug
[INFO][TiAPI   (  327)] info
[WARN][TiAPI   (  327)] warn
[ERROR][TiAPI   (  327)] error
[INFO][TiAPI   (  327)] [log]
