fix: Fix Stop Command when console has pending input

[unknowntrojan]

Description

When executing the stop command whilst something is still typed in the server session (enter was not pressed), the stop command will time out and fail, requiring manual intervention.

Type of change

This pull request simply "flushes" the command buffer by pressing enter. This may cause unintended behavior, such as a typed command getting implicitly executed, but the command will only have an impact on the game state if its persistent between restarts.

Properly execute quit when the session was improperly detached with something typed on the command line.
For example, someone types a command into the server console, then detaches. The stop command will wait, fail and need manual intervention.
