Bug: Schematic: Centered justifications for texts are reset after editing them using the dialog.

Description

It is possible to set text justifications to "center" using the properties panel in the schematic. The corresponding dialog lacks this (new) ability an resets justifications to left/right (horizontal) and bottom (vertical).

Steps to reproduce

1. Add text to schematic
2. Set justification (either one) to "center"
3. Hit "e" to show dialog box, close with "ok"
4. Justifications got reset.
