[TIMOB-10711] iOS: read() method of filesystem not returning blob type for text file

This is not a regression. It exists as far as 2.0.1. This issue also occurs on android. Steps to reproduce: 1) Use the code below and copy the attached text file in the resource directory.

var win  = Ti.UI.createWindow({
    backgroundColor: 'white'
});
win.open();
 
var f = Titanium.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory, 'text.txt');
	
	var contents = f.read();
	Ti.API.info("contents blob object = "+ contents);
	Ti.API.info('contents = ' + contents.text);

2. Notice the logs Expected result: Logs should display results like [INFO] contents blob object = [object TiBlob] [INFO] contents = Hello World. this is a filesystem read test. Actual result: Logs display [INFO] contents blob object = Hello World. this is a filesystem read test. [INFO] contents = Hello World. this is a filesystem read test. Expected results are seen when image file is used instead of text file.
