BTS_Tests: extend TC_early_immediate_assignment: run on trx_nr=1

This patch demonstrates the problem with handling of the Early IA:

* the first part remains unchanged: assign a channel on C0 (arfcn=871);
* the second (new) part tests channel assignment on C1 (arfcn=873).

As of now, osmo-bts does not meet our expectations for the second part.
