Fix tests on Julia v0.7 (#136)

* JuliaLang/julia#22161 updated the parser and
  caused some changes in how Coverage works
* For test/data/testparser.jl, line 10 is the end of a @doc string (`"""
  ->`), and Line 11 is an expression (`f6(x) = 6x`)
* Before the above commit, the zero count goes to line 10, and after,
  the zero count goes (more correctly?) to line 11
