fix(notifications): correctly set the delay from options

[Tentoe]

--notifications-delay was ignored by soutrrr notifications because it wasn't set on creation.

I tested with dockerfiles/Dockerfile.self-contained

Caused by #1377
Probably solves #1485 (needs confirmation)

Indeed. This even shows up as a warning in goland, I wonder why Codacy didn't catch this... Thanks for spotting it!
