tbf/test: Add tests for single and two phase access

These tests cover the message exchange from receiving from the first
RACH request to the first data block when establishing an uplink TBF.

This will be used to check, whether TA and other values are passed to
an MS object correctly.

In addition, the RX RACH log message in rcv_rach is extended to
contain the single block fn.
