fix perceivedLatency being calculated incorrectly (#5013)

* fix perceivedLatency being calculated incorrectly

1. perceivedLatency was previously calculated at
the time of sending STE, but the timeOfLastCharTyped value
is no longer accurate, so calculate the perceivedLatency value
at suggestion showing time to get the most accurate timeOfLastCharTyped

* test fix

* temporarily disable test
