Reset horizontal offset when changing text alignment

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

When using the Alignement section of buttons in the properties panel to align a certain text element, the alignment takes into account the horizontal offset, resulting in not the expected behaviour and mis-aligned text.

1. Create a new score
2. Click on the title and drag it with the mouse a bit to the left or right of the initial position
3. Use the Properties panel (or the new floating text popup) and click on the Alignment buttons to left/center/right align.
4. Observe that the text is not properly centered or aligned to margin, because it has a horizontal offset applied which is taken into account while alligning.

The user expects the text to get aligned to the base box as the button indicates (i.e. exactly in the center or at a margin).

To work around this issue, the user needs to go to the hidden offset box (under the Appearance button) to manually reset the offset to achieve the proper alignment.

The solution I propose is that when clicking the alignment buttons, the horizontal offset to be automatically reset.
