BUG: disable selecting new fiducial if jump slices on

When new fiducials are added to a list, by default that row
in the GUI table was selected. If jump slices is checked,
that would result in the slices jumping to the coordinates
of the new fiducial, which is at the origin when it's first
added. The calculated coordinates are set by a second call
(and produce a second event) in the displayable manager
that was not triggering a second jump to the correct
coordinates. Disable jumping to the newly added
fiducial location when jump slices is on, this limits
the jumping to user clicks in the table.
