Console new line issue right after start

[mpv89]

This is both observable via UART or telnet:
When card boots or connection via Telnet is established, there is a bug where no commanded has been executed yet the auto complete or the first initial command is missing a new line - only the first one.

This is reproduced by starting a telnet session, write 'eeprom.' and press tab for example (or any other command that will auto complete).
After executing one command the bug disappears.
