[BUG] mat-select-search-no-entries-found persists after panel closes

[aronnebrivio]

Describe the bug
mat-select-search-no-entries-found class persists after panel closes. This causes a blank-mat-option-like space before real mat-options until clicking on "X" button to clear filter.

To Reproduce
(based on https://stackblitz.com/github/bithost-gmbh/ngx-mat-select-search-example)

1. Click on the first select input
2. Search for something doesn't exists (like "aaaa")
3. Un-blur the input (both pressing ESC or clicking away), the selector closes
4. Open selector again
   => The list will have a blank option on top (see attached screenshot)

Expected behavior
The _reset() function should be fired also on blur

Screenshots
Before

After

Desktop

• OS: MacOS 10.14.3
• Browser: Chrome
• Version: 72.0.3626.119

Notes
This doesn't happen if there're search results or if the "X" key is clicked to reset the search.
