Motion-block: Change dialog-text for "Follow recommendation for all motions"-action

[Elblinator]

Current behaviour:
The dialog (if you press on the icon) has a wrong wording:

Reproduction:
in a meeting:

1. create motion block
2. activate a recommender
3. create a motion
4. select a motion block and a recommendation (e.g. "Annahme") for the motion
5. got into the motion block
6. press in the top right area on the double tick
7. the dialog should open

Wanted behaviour:
The wording should be changed to: "Are you sure you want to override the state of all motions with recommendation of this motion block? Motions which are already in an Endstate will not be overwritten."

@MSoeb @emanuelschuetze, please confirm or change the wording from 2.
