scale: Remove redundant scale-timer reset from vars.tcl

Scales that have a timer and have ::device::scale::use_timer True
will have their timer reset on entering a flow state, such as Espresso.

Code in vars.tcl would also call ::scale_timer_reset on resetting the
espresso timers, typically at the start of flow.

At the start of flow, a timer-start command is sent. This often
immediately after the timer-clear command from vars.tcl. There is some
evidence that scale hardware may not gracefully handle tight timing.

Rather than introduce a delay, remove the redundant call in vars.tcl
