This also requires a bump to lsp-test to fix a test, and drops the trick that the wrapper tests used to find the wrapper executable since it was just confusing

Need to read in those test results as a file, since the CPP preprocessor trips on those multiline strings Also use @?= instead of `shouldBe`, since the exception thrown by it gets caught by tasty and is pretty printed

I have a feeling the CircleCI tests are failing because of some .stack-work/cache issue, which I can't seem to invalidate the cache for anyway. The tests are passing locally anyway and this is a pretty important fix, so merging anyway |

The bug was caused by broken transitivity of the comparison function used to sort spans. Nested spans were meant to be sorted in innermost-first order, with the first (innermost) one being used to get type information about the symbol at a given position. Because the comparison function considered any two non-nested spans to be EQ, the sort could incorrectly conclude (by transitivity) that two nested spans were equal, and thus leave them in incorrect relative order. This resulted in the innermost span sometimes not appearing at the front of the list of spans which enclose a given point, and hover reporting the type of a bigger expression in which the point appeared. The solution imposes ordering on non-nested spans by comparing their starting positions, thus fixing transitivity. Fixes #237 (... probably along with a bunch of other little bugs caused by the same mistake).
