[TIMOB-24988] Android: Add Ti.Network.Cookie isValid()

[m1ga]

JIRA: https://jira.appcelerator.org/browse/TIMOB-24988

Parity with iOS

Test code

var cookie1 = Ti.Network.createCookie({
	domain: 'example.com',
	name: 'test_cookie',
	value: '12',
	path: '/'
});

var cookie2 = Ti.Network.createCookie({
	name: 'test_cookie',
	value: '12',
	path: '/'
});

console.log("is cookie valid: "+ cookie1.isValid());
console.log("is cookie valid: "+ cookie2.isValid());

No need to set a default value in this case, saves creating empty String objects:

String name = TiConvert.toString(getProperty(TiC.PROPERTY_NAME));
String value = TiConvert.toString(getProperty(TiC.PROPERTY_VALUE));
String path = TiConvert.toString(getProperty(TiC.PROPERTY_PATH));
String domain = TiConvert.toString(getProperty(TiC.PROPERTY_DOMAIN));
return (name != null && value != null && path != null && domain != null);

@m1ga Can you provide a 6_2_X PR as well? Currently this would only go into 7.0.0

FR Passed.

isValid() works as expected.
