#13405 WellAllocationPlot: Fix missing first connection in plot and plot data

The fictitious depth point (-1.0) that extends the topmost connection bar
was only added for accumulated flow on branch 0. For inflow mode and
accumulated mode on branches > 0, the first connection bar had no extent
and was invisible, and the data export skipped the first real connection.
