Allow coverage report to be done on all project files

[Xa3lis]

Clear and concise description of the problem

For now the --coverage only cover file that are currently tested, giving wrong coverage since when only one file is fully tested it give us a 100% coverage when 99% of the project files remain untested

Suggested solution

implementation of the --all from c8 could be great

You can already pass options to c8. This is my config for example.

test: {
  environment: 'jsdom',
  coverage: {
    include: '*/src/**/*.js',
    all: true
  }
}

Property all is not defined in the C8Options typescript interface

[Demivan]

It should still work. Will fix type error in a moment

[Xa3lis]

Dirty fixed for now by doing

coverage: {
    include: ['src/**/*.{ts,vue}'],
    all: true,
} as any
