Missing layout content

[sebbaum]

Describe the bug
If a pattern contains @extends('layouts.app') the rendered output in the main project is missing the content of the layout/app.blade.php file.

To Reproduce
Steps to reproduce the behavior:

1. Create a new Pattern e.g. pages.homepage
2. Add a route to render this pattern
3. Call the route in your browser
4. The rendered page is not styled. The layout file's content is missing

Expected behavior
The page is rendered as if an @include directive is used.

Additional context
The bug is gone, if the call to $this->evaluatePatternStatus($pattern); in PatternServiceProvider::parse() is removed.
