Bug description

When I click the update all button in the integrated app store, only a single app is updated.

Steps to reproduce

1. Go to "Apps".
2. Have at least two apps with updates.
3. Click the "Update all" button at the top.
4. Observe that only a single app is updated.

Expected behavior

All apps should be updated in sequence. It used to work like this before.

Nextcloud Server version

30.0.4.1

On a second press, all other apps get updated at once, though - e.g., when 3 or more updates are available:
First press needs password and only updates the app last on the list, second press updates all other apps at once.

It just worked although I wasn't prompted to confirm my password. This was right after logging in.

This is also still a thing in nc 31.0.5

@st3iny It only occurs when password confirmation is required.
