ListLogs fails to return the right logs when count parameter is not passed

[StefanBS]

When no count parameter is passed the search seems to return the last log in the journal ignoring the match labels.

How to reproduce:
call list_log --params '{"unit": "syslog identifier unit name"}'

Setting a sensible default (count = 1 or count = 10 maybe) fixes this issue
