TYPO3 Core

Test covering the SQL file parser has been streamlined
and enriched with #103602, adding a disabled test with
a todo to enable it with the corresponding bugfix.

Mentally missleaded, the disabled test itself is not
correct based on the fact that MySQL and MariaDB use
single quotes to quote single quotes in values like

DEFAULT 'some value with a '' (single quote)'

instead of the assumed `\'` variant.

Further studies revealed that the prehistoric parser
is more than capable to properly parse this form of
default values.
