chore(android): optimize proxy constructor lookup

[garymathews]

• Minor optimization for V8 proxy constructor lookup
• Prevent unnecessary GetPropertyNames() call
• Correctly sets prototype constructor
  • This means exports->GetConstructorName() returns the proxy name

Related Object.constructor

TEST CASE

const win = Ti.UI.createWindow();
const label = Ti.UI.createLabel();
const label_derived = new label.constructor({ text: 'This is derived from a constructor.' });

console.log(`label.constructor: ${label.constructor}`);
console.log(`label_derived.constructor: ${label_derived.constructor}`);

win.add(label_derived);
win.open();

@garymathews, this change somehow prevents our "bootstrap.json" from being read on app startup. It happens to both encrypted and unencrypted builds. The following error will be logged, which you can see in Jenkins' output. I'm seeing this error on my end too.
Failed to read "bootstrap.json". Reason: Unexpected token u in JSON at position 0

This causes our "hyperloop-examples" sample app to crash.

CR/FR: Pass

Tested the following:

• kitchensink-v2
• hyperloop-examples
• Building module "ti.map" with this PR and using it in a 10.1.0 and 9.1.0 built app.

FR Pass, in addition to Josh's testing I also tested webpack and liveview usage
