Activate typechecking in non-lsp mode

• Fixes haskell-language-server 0.1 stops before checking files #84

[Philonous]

The haskell-language-server executable now tries to type check the project, but the ghcide that is installed alongside it still stops after step 4/6.

[jneira]

@Philonous ideally the ghcide executable should not even be built in this project: we use ghcide as library in a submodule that points to other repo but we cant exclude (easily) the executable from the build. So, in general, fixes in the ghcide executable should belongs to ghcide itself (well actually the fork we are using: https://github.com/mpickering/ghcide/tree/hls)

That said it is a tiny patch and i will open another one upstream

[Philonous]

@jneira That is fair enough, and I don't really mind, I just wanted to let you know in case you missed it.

[jneira]

@Philonous yeah, thanks for that i only want to clarify the relation between hls and ghcide, it is a little bit blurry, even for me! 😄

It turned out that it is already fixed in https://github.com/mpickering/ghcide/tree/hls so all done here
