Fix: too many calls to getSuggestedWordsForTypingInput

This reverts commit d941ea18 and builds on it to fix the behavior
of the broken cases.
It also fixes a small, related bug that probably has existed for
a very long time: predictions not displayed when cancelling
double-space-to-period.

Bug: 15148015
