md-autocomplete: Should create an ellipsis before the x icon

[epelc]

md-autocomplete should handle longer text better. Right now it just keeps showing it behind the x icon. Perhaps it could create an ellipsis before the x icon or at least no go behind the icon.

I think it's a duplicate of this issue : #2193

@jgoux They are very similar but I'll keep this open to document the text going behind the x.
