Upgrade Wizard for FAL references SQL error on missing tables
If you have some sys_file_references pointing to tables that no longer exist in your installation (some extension that was deleted and the tables also deleted), you end up with SQL errors in the Install Tool when calling the Upgrade Wizards:
ERROR Table 'typo3.buggy_table' doesn't exist
lastBuiltQuery SELECT uid, pid FROM buggy_table WHERE uid=0 AND pid<>0 LIMIT 1
So the proposal is to use the same upgrade wizard which is already cleaning sys_file_reference to get rid of these buggy entries, while also fixing this SQL error bug.
How to reproduce?
Simply add a row to sys_file_reference with "pid=0" and "tablenames" pointing to some tablename that doesn't exist.
[TASK] Upgrade Wizard for FAL references, check for missing tables
In case sys_file_reference contains references to tables that no longer
exist physically (i.e. for extensions that were deinstalled and tables
then deleted through "Database Compare"), the sys_reference_table
upgrade wizard now no longer fails with an exception. Instead the buggy
rows will be deleted from the table.
