LSP: Crash when aliasing a module

[spotandjake]

The following code causes the lsp to crash with a Not_Found:

from "./host.gr" include Host
use Host.{ module Bindings as A }
print(A.add(1ul, 2ul))

the issue seems to come from aliasing in the module Bindings as A the exception seems to be thrown from Sourcetree when we call find_module, we could fix this by just adding a try catch and not including the item in sourcetree but that just hides the bug and I think this is indicative of a deeper problem. This exception happens when the didOpen event fires.

After investigating this a little I think the problem here is actually in find_module comparing to find_name if we do not find the given ident in the IdTbl we then check the alias table before declaring it not found this logic does not currently exist in the find_module function.
