ghcup set is not run when the desired ghc version is found in the cache #36

I am having this issue on a MacOS github hosted runner with this action:

    - uses: actions/setup-haskell@v1.1
      name: Setup Haskell
      id: setup-haskell
      with:
        ghc-version: 8.8.4

The output from setup-haskell is:

Preparing to setup a Haskell environment
Resolved latest to 3.2.0.0
▼ Installing ghc version 8.8.4
  Found ghc 8.8.4 in cache at path /Users/runner/.ghcup/ghc/8.8.4/bin. Setup successful.
▶︎ Installing cabal version 3.2.0.0
▶︎ Setting up cabal

But running ghcup list later in the workflow shows

✗  cabal 3.4.0.0-rc3 prerelease                       
✗  ghcup 0.1.11      latest,recommended

and any ghc commands use ghc-8.10.2 instead of the requested version (8.8.4).
