Steps to Reproduce:

1. Create a new js file
2. Type:

let obj = {
    a() {},
    async b(

3. After typing the ( after async b, it is autocompleted to blur(). Note how the non-async method a does not autocomplete.

I think this is unexpected, as I'm creating a new method same as a, so it shouldn't autocomplete the word.
Similarly, if I do a generator *: * c( it also autocompletes.

Also, computed properties [] do not autocomplete, maybe they should? e.g. [pf( should autocomplete to [parseFloat() I would think?

The root cause of this seems to be that isNewIdentifierLocation is false after async. We use isNewIdentifierLocation to suppress commit characters
