Current behavior
If you have a component without style tags, it disappears from the coverage.
Adding an empty style block fixes this.
Expected behavior
Should still show up in coverage even without <style> tag

Minimal reproduction of the problem with instructions
Take any starter project for jest-vue, add a single file component - delete the style tag, run coverage.

What is the motivation / use case for changing the behavior?
Less wtf moments ;)

• jest-vue-preprocessor: 1.1.X
  1.3.1

• Node version : [ OSX ]
  8

• Platform: [ OSX ]

This is not a big issue, just so if anyone else is pondering this - they can see why it's not working.

Also, removing mapCoverage from jest shows the missing file, but screws up the line obviously.

I was having the exact same problem, couldn't figure out why it wasn't showing up on coverage, found this and tried adding the style tag and now it works.
