add default type attribute for input element

[technohippy]

Now <input ng-model="myModel" /> does not work because there is not any type attribute. This patch makes this work.

Thank you for your quick reply. I signed it electronically just now.

Could you add a test to this PR? Other than that, this looks like a good change.

[technohippy]

I added some tests although they are just copy-and-paste.

I'd rather test than the type="text" attribute is added which is what the code does.

Please also check CONTRIBUTING.md for commit guidelines. Thanks.

I added a test to check that the type="text" attribute is added.

An other option would be to implement :not in the selector.

You are right. Honestly I tried it first but it's beyond me.
