TokenizingTextBox does not unselect all Tokens on LostFocus

[minesworld]

Describe the bug

If a Token is selected (higlighted with blue) it will loose that focus and higlight if the AutoSuggestTextBox gets the focus.

But if the TokenizingTextBox looses its focus a selected Token will still retain its selected status and remains highlighted.

TokenizingTextBox.cs

private void TokenizingTextBoxItem_LostFocus(object sender, RoutedEventArgs e)
{
    // Keep track of our currently focused textbox
    [ ... ]

    DeselectAllTokensAndText();
}

Adding the DeselectAllTokensAndText(); should fix that.

Steps to reproduce

- create a Token
- click on it
- click on a TextBox other than the TokenizingTextBox containng the Token

Expected behavior

All Tokens should be unfocused too if the TokenizingTextBox looses its focus.
