Log initial state after enabling WM tracing

Currently the traces are logged only if a transaction is commited. The
initial trace should be logged when starting the trace, as it is useful
for debugging

Test: Flash a device. Start WM tracing. Don't use the device. Stop WM
tracing. Open the trace in Winscope, it should have 1 entry
