stack ide start fails to start if the project has compile errors #810
Description
This gist has the minimal failing example. The expected behaviour of stack ide start is to start up stack-ide even if there are compile errors. However, stack now tries to build the project first which fails with compile errors:
$ stack --version
Version 0.1.3.1, Git revision 28a8f6a643d43a1cdbd3d2bc734359e4b74c7255
$ stack ide start --verbose
Version 0.1.3.1, Git revision 28a8f6a643d43a1cdbd3d2bc734359e4b74c7255

This reminds of the nightmarish behaviour of cabal-installs cabal repl, which would fail to start up unless everything built fine, making developing ide plugins (as well as just trying to use the repl) a real pain.
