Remove unecessary app logic (fix #1213)

[J0WI]

Fix #1911

[joshtrichards]

Seems fine if this goes away since it was just a passive partial remedy. But perhaps we should create a follow-up issue?¹²³

This seems like something that needs to be nudged upstream to get addressed in Server itself rather than in the downstream images/packagers.

Footnotes

1. I'm not sure the root issue (of the upstream app update logic not always being robust enough) is fully addressed. AIO actually does more at this point (after originally doing what this PR removes). ↩

2. Basically to collect data on upgrade problems that are app related and to, maybe, evaluate what (if any) benefits there might be to taking AIO's approach (at least until any deemed appropriate upstream changes are made). ↩

3. make update process more stable all-in-one#1420 AIO replaced the code under discussion in this PR with a broader scope improvement to make upgrades more robust in Think about making update process more stable all-in-one#1400 / make update process more stable all-in-one#1420 ↩
