### Describe the bug
Using autocomplete to create a stub definition of a `func` within a struct, the aliased package names for the dependent types aren't preserved.  Instead, the non-aliased package names are used.

### Steps to reproduce the behavior:
Clone https://github.com/jhendrixMSFT/autocompleterepro
On line 12, note that the package names for `resp` and `errResp` are incorrect.  They should be `azfake` but are `fake`.
To repro, just delete line 12 then recreate it, using the autocomplete prompt to create the stub definition for `Get`.
