"No results found" can be misleading

[chucker]

Is your feature request related to a problem? Please describe.

The <LanguageSelection> component will say "No results found" if something isn't in the drop-down source. This can happen for two reasons:

• we don't have that language available (or that language doesn't exist at all)
• you've already picked the language

Describe the solution you'd like

If you've already selected the language, the UI should reflect that, as it's otherwise confusing.

Additional context

I'm not sure this is easily possible. BlazoredTypeahead just invokes Search, then gives that message if that returns an empty enumerable.
