mdAutocomplete: md-not-found template flashes before items are displayed

[nfriend]

The md-not-found template is briefly (as long as half a second) shown before the md-autocomplete displays its result set.

See this in action here: https://jsfiddle.net/NathanFriend/Lctcxjqr/

Expected result: the md-not-found template should never be shown if the query returns at least one result. The examples at https://material.angularjs.org/latest/demo/autocomplete don't exhibit this issue.

Some additional information:

Angular Material Version: 1.0.3
Angular Version: 1.4.9
Browser and OS: Chrome 47.0.2526.111 on Windows 8.1

Just investigated a bit, the problem is, the autocomplete will set the loading state to false if a previous promise is resolved. So when you search for A-R-I-Z-O-N-A (normally typed - not pasted) there will be a promise for each char. So the state of setLoading will change to false. This can be solved by adding a simple fetching queue. But only check the queue on the promise finally to store the retrieved results in cache.
