Two parallel learner-tooltip systems both rendered on unit hover, so with
the 'Use secondary learner tooltip' option on, learner spawn/kill lines
still leaked into the main NPC tooltip instead of going solely to the
secondary frame.
QuestieLearner's OnTooltipSetUnit hook (toggle-aware, secondary-capable)
already owns unit-hover learner display, routing it to the main tooltip
(secondary off) or the separate secondary frame (secondary on). But
Tooltip.lua's _GetLearnerTooltipLines also injected learner lines into the
m_<npcId> tooltip data, redundantly.
Add a suppressLearnerLines flag to QuestieTooltips:GetTooltip and pass it
from the NPC unit-hover call in TooltipHandler so the inline lines are
omitted there. Map-pin and object tooltips (no secondary frame) keep their
learner lines. Also removes the latent duplicate present even with the
secondary frame disabled.
