No completion or signaturehelp/hover for module aliases

[non-Jedi]

For longer module names one common pattern I use is:

using FooBar
const FB = FooBar

f() = FB.foo()

The language server does not provide completion for foo in this scenario and when hovering over foo, no signatureHelp/hover is provided. Jumping to definition textDocument/definition also doesn't work.

I am on master but still not getting completions for aliases
