maude_decom.get_aca_packets from blobs does not handle blobs argument and does not pad stop time

[javierggt]

These are actually two issues in maude_decom.get_aca_packets:

• the blobs argument is ignored
• it gives inconsistent results when using blobs or frames. In the case of blobs, the last few packets are missing. This can happen when makes the query without adding some padding at the end, to allow for trailing packets, but I believe I added enough padding for that, so I need to check why this is happening.

The following test fails:
