fix: path replace fail when dirname has same ext

[heycalmdown]

There are some projects which have an extname on its project name. According the results of the query from npmjs.com... - https://www.npmjs.com/search?q=.js

• https://www.npmjs.com/package/popper.js
• https://www.npmjs.com/package/big.js
• https://www.npmjs.com/package/hash.js
• https://www.npmjs.com/package/reveal.js

Let's say that we are making a project named abc.js on TypeScript; We are building something on the directory like below,

/Users/heycalmdown/development/abc.js$ npm run lcov-remap

The coverage/lcov.info will start with

TN:
SF:/Users/heycalmdown/development/abc.js/dist/index.js

And the remap file starts with

TN:
SF:/Users/heycalmdown/development/abc.ts/dist/index.js

Expected result is

TN:
SF:/Users/heycalmdown/development/abc.js/dist/index.ts

Thanks for the fix, the test failure is due to other things, so I've gone ahead and landed this.
