Fix multi source directories

[fendor]

Closes #1576

@tuomohopia Would you mind testing if this fixes your issues?

Some azure jobs are failing cause cabal-helper are trying to install Cabal-3.0.1.0, weird

haskell-ide-engine>   test/unit/CabalHelperSpec.hs:63:5: 
haskell-ide-engine>   1) CabalHelper, cabal-helper spec, cradle discovery and loading, existing projects, implicit exe

Tests don't work yet, opening a test file in the editor would give the same error:

2020-01-20 00:09:39.7838711 [ThreadId 625] - Fail on cradle initialisation: (ExitFailure 2)["Could not obtain flags for: \"test\\integration\\AnswersEndpointSpec.hs\".","","This module was not part of any component we are aware of.","","Component: ChLibName ChMainLibName with source directory: [\"src\",\"src/schema\",\"src/api\",\"src/Questions\",\"src/Users\"]","Component: ChExeName \"healthbot-api-exe\" with source directory: [\"app\"]","Component: ChExeName \"migrations\" with source directory: [\"migrations\"]","","","To expose a module, refer to:","https://docs.haskellstack.org/en/stable/GUIDE/","If you are using `package.yaml` then you don't have to manually expose modules.","Maybe you didn't set the source directories for your project correctly."]

However, as far as I can tell everything else works normally again!

@tuomohopia Yes, this does not aim to fix the tests but rather the observed behaviour with your main library. Fixing the problem with the test components is more elaborate and discussed at: DanielG/cabal-helper#92

@jneira Any ideas what is going wrong or any fixes?
We could make components loads dependent on the current build tool to execute?

Sorry i missed the mention, let's see how finish this run but i am very surprised to see a build of a version of a library not released

[fendor]

@jneira No problem! I disabled loading of components by cabal-helper to get this PR merged asap, so now we return to the status quo of the test-suite.
Situation should be improved by #1585
