Partial code coverage or incorrect mapping

See original GitHub issue

Issue

Hi and thanks for all the job done for this library 👍

I have probably the same issue as https://github.com/kulshekhar/ts-jest/issues/339 but with a single repo. The solution pointed in the issue is not suitable in my case.

I either have an incorrect code mapping on coverage without "mapCoverage": true or missing files when this option is removed + an almost correct mapping.

Incorrect mapping + all files covered

Expected behavior

Having correct code mapping on coverage report without missing covered files.

Any help would be greatly appreciated.

Looks that after I upgrade to Jest 23.4.2 and ts-jest 23.1.3 the coverage is mapped correctly. Thank you guys!
