[TIMOB-26545] Android: Using global L() method for localization does not work if second argument is not supplied

If the L method does not receive a second parameter, the fallback string is not displayed if not supplied as a second argument. This works fine on iOS. Example:

// Works
L('Hello world', 'Hello world');

// Does not work on Android, works on iOS
L('Hello world');

This triggered TIMOB-26544 and is kind of a blocker for us. *Update*: We now implemented a workaround using the ti.shell feature (in a L.bootstrap.js):

global.Lx = (value, comment) => {
    return L(value, comment || value);
};
