HLS crashes when triggering module names completion

[berberman]

HLS verson:

haskell-language-server version: 0.9.0.0 (GHC: 8.10.3) (PATH: /home/berberman/.cabal/store/ghc-8.10.3/haskell-language-server-0.9.0.0-0a1f130421b85b97d7d539f51f666b79f189459c3d06c11eb1bfa9e18e0dbb5d/bin/haskell-language-server)

relevant log from output:

	ModOrigin: hidden module redefined

Please report this as a GHC bug:  https://www.haskell.org/ghc/reportabug

I think it's related to a reported ghc bug: https://gitlab.haskell.org/ghc/ghc/-/issues/16996 -- HLS crashes only when loading projects where we are not able to use module completions in ghci, as discussed in the gitlab issue.

This was also discussed in #786

@berberman this can be closed by #1367 or we could do something to improve state of things?
I guess it is blocked on the mentioned ghc bug

I'm assuming this is fixed
