Make "name" column nullable for workflows

[PVince81]

The "name" column is now unused and the code is always inserting an
empty string. While this works with most databases, Oracle complains
because an empty string is equivalent to null.

To fix this, the column definition is changed to allow null values now.

Also added some logging in case of database exceptions, because without
this nothing would be logged to detect the above problem.

note, I've seen in the JS code that this column is actually legacy and not used any more, see https://github.com/nextcloud/server/blob/master/apps/workflowengine/src/store.js#L105

so probably in the next major version we could remove it completely.

but here I needed a small less impactful fix that we can backport

PHP Warning:  require(/drone/src/lib/composer/composer/platform_check.php): failed to open stream: No such file or directory in /drone/src/lib/composer/composer/autoload_real.php on line 25

okay....

weird, so build/autoloaderchecker.sh has generated a new file that did not exist before: lib/composer/composer/platform_check.php

I'll git add it but let me know if this is wrong...

[PVince81]

failing test is unrelated, the previous run had a different integration test failing

@juliushaertl can you recheck ?

another weird thing is that apps/workflowengine has a composer folder but no composer.json file, so the dump-autoloader function fails with "No lockfile found. Unable to read locked packages".

so how are we supposed to update the autoloader files in apps with autoloaderchecker.sh ?

or maybe it's the newer composer that refuses that.
when I run the script it downloads and installs composer 2.1.5.
this is with php 7.4.21

[PVince81]

I've asked Arthur to run the script locally and he mentioned no issues when updating, with the same composer version and PHP 7.4.15

so maybe there's something strange in my environment, I'll debug this locally

[PVince81]

I've managed to clean the autoloader mess by running the script on a different environment.
For some reason on my local dev env composer behaves differently.

Please recheck
