fix(startup): set full_screen when in ex_mode

Problem Description: In ex_mode, the default_grid.chars are not allocated, and subsequently,
the w_grid.target in curwin is not allocated to default_grid in update_screen. This leads to
a null pointer crash when the completion function is executed in ex_mode.

Solution: Set full_screen when in ex_mode to ensure that default_grid is allocated.
