switched to from_file=False for hlt2_all_lines test follow-up
from !3106 (merged)
"When using reconstruction from old brunel files with from_file=True, the unpacking is done using different algorithms than what we use for Moore output. While new unpackers can unpack all dependencies, old unpackers require dependencies to be unpacked explicitly. In this particular case, tracks in the PV are not unpacked but requested to be packed with PVs when pv_tracks=True.
Providing a proper fix will take time and not clear if it's worth it, so this should fix the tests for now."
