[Xsquash4Jira | Jira Cloud] Pagination fails when adding synchronization for 50+ tickets

Affected version : certainly 10.2.6, xsquash4jira 11.0.2 & 12.0.0.IT6

Since the recent fixes for the Atlassian /search deprecation, pagination is broken:
When my synchronization scope contains more than 50 tickets, the tickets are created in batches of 50 on every synchronization cycle.

Steps to reproduce

Configure a synchronization with Jira Cloud and scope must have more 50 tickets.
The synchronization interval must be long enough to observe that the requirements are being created in batches of 50.
