We need to check with @Archidoit what was the goal of the previous code

[Archidoit]

@Kedae this was to update the instance triggers list in case the user had deleted/updated one of triggers via the quick subscription edition panel

[Archidoit]

but seems to work without it now that the 'pagination keys' are the same as Céline told me , strange

[Kedae]

I read wrong Cathia's message, we need to discuss it
