Describe the bug

• Reporter error is silenced when --merge-reports #9642
• fix: don't silence reporter errors from test runtime events handler in normal run and --merge-reports #9727 (comment)

Not only --merge-reports, but normal test run also silences reporter errors that are thrown during test runtime event such as onUserConsoleLog.

• repro.test.ts

import { test } from 'vitest';

test('foo', () => {
  console.log('test-crash');
});

• vitest.config.ts

import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    reporters: [
      'default',
      {
        onUserConsoleLog(log) {
          if (log.content.includes('test-crash')) {
            console.log('throwing an error from Reporter.onUserConsoleLog!');
            throw new Error('reporter error during onUserConsoleLog');
          }
        },
      },
    ],
  },
});

Test finishes with no errors:
