TDDFT restart: `efield_*.dat` file incorrectly appended when calculation restart

[AsTonyshment]

Describe the bug

In TDDFT calculations, when performing a restart, it is necessary to continue applying and recording the electric field information to the efield_*.dat file. The electric field should be applied starting from the current time step of the restart. However, in the current implementation, the electric field seems to be incorrectly reapplied from $t=0$, causing inconsistencies in the system's state before and after the restart.
