Make our usage of this more uniform.

Create Pleroma.Maps.put_if_present(map, key, value, value_function // &{:ok, &1}) :: map

See merge request !2436

Unifies all the similar functions to one and simplify some blocks with it.

This is to run things like streaming notifications out, which will
sometimes need data that is created by the transaction, but is
streamed out asynchronously.

As the notification type changes depending on the follow state,
the notification should not be created and streamed out before the
state settles. For this reason, the notification creation has been
delayed until it's clear if the user has been followed or not.

This is a bit hacky but it will be properly rewritten using the
pipeline soon.

This is to prevent wrong values in the stream.
