Extract the IMSI from the first message as well and safe it
in the connection structure. The problem is that we do not
have this structure at this point, so we will allocate the
imsi as child of the bsc_connection and then move/steal it.

...
Currently it is not is not easily possible to disable
everyone and then only allow certain SIMs. By changing
the order we can do:
access-list imsi-deny only-something ^[0-9]*$
access-list imsi-allow only-something ^123[0-9]*$
and still keep the usecase of only forbidding certain
SIMs on certain LACs. Adjust test case, test that the
other cases are still functional.
