Test failing on coverage does not print exact location

[owickstrom]

In #308 we added the location information of failed assertions. Conversely, it would be great if failed coverage checks also print location information. But it turns out they do not:

  ✗ prop_example failed 
    after 100 tests.
  ⚠ large 0% ···················· ✗ 1%
  
        ┏━━ Example.hs ━━━
    144 ┃ prop_example = property $ do
    145 ┃   n <- forAll (Gen.int32 (Range.linear 0 10))
    146 ┃   cover 1 "large" (n > 10)
        ┃   ^^^^^^^^^^^^^^^^^^^^^^^^
        ┃   │ Failed (0% coverage)
  
    Insufficient coverage.
  
  ✗ 1 failed, 1 succeeded.

I'd like for it to have location information, and thus print:

  ✗ prop_example failed at Example.hs:146:3
    after 100 tests.

I haven't yet dug into why this might be. Might try to get a PR up within the coming days.
