Add weight to sideEffects

[Benno]

🐛 Bug report

🤖 Current Behavior

It can happen, that the 'rebuildStorageSideEffect' gets called before the the 'rebuildGroupSideEffect' than it stores the
not rebuild value..

Currently we are lucky, that the 'rebuildGroupSideEffects' got added before the 'rebuildStorageSideEffect'..
but that might not be always this way

💡 Suggested solution(s)

Add a weight to the sideEffect, to see in which order it should get exectued!!
