Warning message if clangd not found not displayed ?

[Alexander Neundorf]

Hi,

I digged a bit into my clangd problems, and got a little bit further.
If clangd is not installed (it doesn't crash anymore, I think it did in older 
versions, that's good :-) ), 
In LSPClientServerManagerImpl::_findServer() it ends up in the branch 
"we didn't find the server at all!", where a warning should be displayed using 
showMessage(), but I can't see the warning. "LSP Client" -> "More Options" ->  
"Show Messages" is checked. 
Where should the message appear ?

(next step would be to find out how later on my clangd command line ended up in 
the Blocked-list...)
