MGCP_Test: add new testcases for oa/bwe conversion

The octet aligned to bandwith efficient conversion is currently only
tested in scenarios where only one codec is assigned on both sides.
However, there may be call agents that will assign bandwith efficient
and octet aligned on one side for compatibility reasons. If this is the
case, then OsmoMGW should always chose the format that requires no
conversion.
