Look at re-deprecating Session::recursivelyApply()

[emteknetnz]

Session::recurisivelyApply() is currently deprecated

I've undeprecated it as part of this issue because the recommended migration to Session::recursivelyApplyChanges() has a different API

I've split off this card to look at re-deprecating this separately after the bulk of the deprecation changes have been made.

Acceptance criteria

• Code pointing to Session::recurisivelyApply() is updated to use Session::recursivelyApplyChanges()
• Session::recurisivelyApply() is deprecated

Notes

• Because this is low priority, this doesn't have to happen in time for 5.0.0
