bsc: TC_paging_500req: Validate initial transmissions have higher prio

After osmo-bsc Change-Id I1ae6d97152c458247bc538233b97c2d245196359, initial requests are prioritized over retransmits. Before that feature was in place, when sending 500 requests in this test to the BSC, it could happen that the paging scheduler triggered (every 500ms) before all the 500 requests were received at the BSC. As a result, the scheduler would put some requests to the end of the queue after sending an initial request for it towards the BTS. If later more requests where received from TTCN3, they'd be put at the end, after the retransmissions. As a result, the emulated BTS would in general receive retranmits for the first bunch of requests before receiving the initial transmit of the later requests. Ths is no longer the case since the osmo-bsc is prioritizing now the initial requests. Hence, we'll only start receiving retransmits after all the new paging requests are received.
