line number incorrect even in a simple example (Node 7 and no React)

[Tuizi]

• Issue
  Line number in coverage result table are not correct. The line number sometimes correspond to an empty line or a line with a }.
  I know that there is an issue with line number when using Node 8 and React 16, but I just did a small example using Node 7 and without React... Pure Typescript and line numbers are not correct.

• Expected behavior
  Line number in the coverage result should match line of the Typescript files

• Link to a minimal repo that reproduce this issue

Clone https://github.com/Tuizi/ts-jest-issue-repo and npm install && npm test

"mapCoverage": true, in seems to be the solution for my issue.

For anyone stumbling upon this late, the mapCoverage Jest option was removed and its behavior has been enabled by default. See here: jestjs/jest#5177
