fix namespace bug in _logs()

[pinheadmz]

There is a leftover bug from #651 that prevented the Battle signet miner command from working:

Command:

(.venv) --> warnet run scenarios/admin/signet_miner.py --source_dir=scenarios --tank=0 generate --min-nbits --address=$(warnet bitcoin rpc miner getnewaddress) --ongoing --debug

Error:

Error getting pods. Could not determine primary container: cannot access local variable 'pod_namespace' where it is not associated with a value

[mplsgrant]

ACK. Works for me.

edit The namespace component works for me, but the command in op does give me this error:

Waiting for commander pod to start...
/bin/sh: 1: Syntax error: "(" unexpected
Deleting pod...
pod "commander-signetminer-1729005660" deleted

update: I needed to create the wallet and have the miner tank up and running, and that allowed the command in op to run!
