Material: mdChips with mdAutocomplete: readonly lets floating label disappear on autocomplete

[migingreen]

See md-chips autocomplete example with additional readonly checkbox and autocomplete with md-floating-label instead of placeholder:
http://codepen.io/anon/pen/NNqzQV

There are several issues present:

• The md-chips disappears completely if there's no value present and set to readonly (related to #7136 )
• Floating label (same for placeholder) disappears if value is present and set to readonly
• md-autcomplete input-container (with floating label) doesn't align with md-chips

Floating labels should always be visible in my opinion, most of the time there are more than just one input field present in a form which leads to confusion if some inputs have no label.

Possibly related to #3200
