Add braces around context part.
In the HNBGW_Tests.ttcn output, I see this:
DRUA DEBUG TTCN3 HNodeB transmitting RUA DirectTransfer
which reads like the hNodeB would transmit a RUA to us. Instead, this is
us sending RUA to the hNodeB, which is much clearer like this:
DRUA DEBUG (TTCN3 HNodeB) transmitting RUA DirectTransfer
This matches the way we typically show context info in osmo logging.
