Move eboot_command_clear to after firmware copy. (#6823)

Browse Source 
The eboot command was cleared from the rtc mem before the firmware copy
making it possible for a power failure during an OTA update to brick the
esp until the firmware was loaded via USB because of a partial firmware
copy that would never be restarted.

Moving the eboot_command_clear to after the copy ensures that any partial
copy is restarted at next power on.
