Applying a barline from the palette with `Ctrl` held should split the measure at the same position as without `Ctrl`

[bakajikara]

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

When applying barline from palette, pressing Ctrl creates barline to a different position than not pressing it.
In #16641, the position where a barline is created when applied from the palette was changed, but this change should also have been applied to the position where the measure is split when Ctrl is pressed.

1. Select note on the score
2. Apply barline from the palette without Ctrl. This creates barline after the chordrest. (expected)
3. Apply barline with Ctrl. This creates barline before the chordrest. (not expected)
