Server: Failed to enable app workflowengine

[MichaelHeimann]

Steps to -reproduce-

1. have nextcloud 10.0.3
2. upgrade to 11.0.1 via web updater

Comment:
As nickvergessen posted here (https://github.com/nextcloud/server/issues/2617) that this might happen it the upgrade was already done in the past: it wasn't.
The upgrade succeeded as far as I can say - no issues observed and the occ app:list doesn't give a version for the workflowengine, so I guess it's fine.

Expected behaviour

No error.

Actual behaviour

upgrade error'd: "Failed to enable app workflowengine"
needed to upgrade via occ upgrade on cli

@nickvergessen I've just upgraded from 11.0.1 to 11.0.2 and again this error. (workflowengine: Failed to enable app workflowengine)

I've not restored a backup before as mentioned in #2617. The Script you reference to, gives me "App workflowengine is not installed and disabled 1488233735 [Error] Table flow_checks of app workflowengine exists although the app is not installed 1488233735 [Info] Table flow_checks has 0 entries 1488233735 [Error] Table flow_operations of app workflowengine exists although the app is not installed 1488233735"

What is this workflowengine thingy, I can't remember installing or uninstalling it. Do I need it? How do I not get this error when I do the next upgrade?
