Filled Drupal dump has a syntax error

Problem/Motivation

The filled dump has a syntax error:

Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in /var/lib/drupaltestbot/sites/default/files/checkout/core/modules/system/tests/fixtures/update/drupal-8.filled.standard.php.gz on line 59555
FATAL Drupal\system\Tests\Update\UpdatePathTest: test runner returned a non-zero error code (255).

Proposed resolution

Use the manual fix from Gabor in #2554151: Test content/configuration in update database dump:

So the dump is problematic... That line is the source line from:

values(array(
  'lid' => '7120',
  'source' => "<strong>Reminder: don't forget to set the $settings[&amp;#039;update_free_access&amp;#039;] value in your settings.php file back to FALSE.</strong>",
  'context' => '',
  'version' => 'none',
))

Remaining tasks

User interface changes

API changes

Data model changes
