Do not update the bound value on connection

Hi! This is a PR for #141.

Thanks

Hello, I have a few notes:

I can't seem to reproduce the issue. the jsbin does not seem to run properly, also I fear that this is a large breaking change. Also, I believe this was an intentional change for polymer 1 migration backwards compatibility.

Finally, please run the format script so that the tests can run.

Hi!

I fixed the JSBin and it's reproduced now. But I can't run npm run format command. It fails using npm and yarn. Windows and Linux.

The error is:

$ npm run format

> @polymer/iron-input@ format C:\Work\Starcounter\iron-input
> webmat && npm run update-types

> @polymer/iron-input@ update-types C:\Work\Starcounter\iron-input
> bower install && gen-typescript-declarations --deleteExisting --outDir .

Worth mentioning that it works on master but not on 2.x branch.

You can manually do the format as well; the diff should be in the travis failure. The error seems to be related to updating the typescript types, but this PR doesn't look like it will change them.

I am going to have to take a longer look at this as this is a breaking change and as I'm in the middle of a large internal migration of this element.

Thank you so much for being so responsive.

This is still in the process. Progress is unfortunately slow due to huge refactors in paper-input
