Fix "ReferenceError: true__options__ is not defined"

[dschmidt]

No idea if this is the cleanest approach, but at least it fixes the following error for me:

 FAIL  packages/....spec.ts
  ● Test suite failed to run

    ReferenceError: true__options__ is not defined

This is caused by a missing newline before the __options__ in the generated code.

before:

var staticRenderFns = []
render._withStripped = true__options__.render = render
__options__.staticRenderFns = staticRenderFns

with this PR:

var staticRenderFns = []
render._withStripped = true
__options__.render = render
__options__.staticRenderFns = staticRenderFns

For the record: this is with Vue 2.7

I am seeing this error too, but only on Github CI. On my dev machine, this doesn't happen. I'll add some info below, which I would normally add to an issue, but since there is no issue and only this PR I'll add here.

These are a few of the related Vue versions:

Are you using a lockfile and the same versions on your dev machine and in CI?

[cjrh]

Absolutely. It's a real mystery.

[PKatrimoustakis]

I am running into the same issue in CI and the fix proposed here alleviates it. To reproduce it locally make sure you've cleared your Jest cache.

[cjrh]

Aha, the jest cache is why I got different results. Thank you @PKatrimoustakis

[lmiller1990]

Nice job, I'll merge and release this for you once CI passes.

[lmiller1990]

I released it, please give it a try: https://github.com/vuejs/vue-jest/releases/tag/v29.2.1

[dschmidt]

Works for us! Thanks!
