[TIMOB-24053] Android: Fix Ti.UI.TextField passwordMask when not editable

[garymathews]

• Allow passwordMask to be set correctly when editable is set to false

TEST CASE

var win = Ti.UI.createWindow({backgroundColor: 'grey', layout: 'vertical'}),
    txt = Ti.UI.createTextField({value: 'hello', editable: false, passwordMask: true}),
    btn = Ti.UI.createButton({title: 'SHOW/HIDE'});

btn.addEventListener('click', function () {
    txt.passwordMask = !txt.passwordMask;
});

win.add(txt);
win.add(btn);
win.open();

I think the description is backwards, this fix is for when editable is false. In any case, I verified the broken behavior on an old SDK, and the fix with this PR. LGTM 👍
