Remove useless code (A63)

If the separator is not a space, then we will always call
setPunctuationSuggestions and reset the suggestion strip anyway.
If the separator is a space, then the cursor has a space on
the left, which means isCursorTouchingWord depends only on
whether it touches a word on the right. If we were displaying
the "add to dictionary hint", it means a suggestion was just
chosen, so it had to be displayed, and that requires a composing
word and no non-separator at the right of the cursor.

In the end, if we go through this postUpdateSuggestions call,
we are sure we will reset the suggestions later in this method,
either by calling postUpdateBigramPredictions, or
setPunctuationSuggestions.
