servant-elm-0.4.0.1 test suite failure with servant-0.13

As seen on the Stackage build server:

I was able to reproduce the failure locally like so:

stack unpack servant-elm-0.4.0.1 && cd servant-elm-0.4.0.1
edit stack.yaml # add the following stack.yaml
stack test

# stack.yaml
resolver: nightly-2018-03-10
extra-deps:
- servant-0.13
- http-types-0.12.1
- servant-foreign-0.11

It is unclear to me whether this is a testing fluke, or a legitimate regression in servant-elm or one of its dependencies. For now, I will mark xlsx as an expected test failure on Stackage.

@DanBurton thanks, yes this was a legitimate regression. Fixed in #31 and released to Hackage as 0.5.0.0.
