Hide the autocompleter intelligently when you ignore it and keep typing

Browse source 
Summary:
Ref T10163. When we think the user has finished typing a word (because they typed a space, period, or other similar characters) and nothing else they might type could possibly change the outcome (usually because the words they have typed already match nothing), just deactivate the autocomplete.

As a special case, if the word they have typed already select exactly one result, //and// they have already typed exactly that result,  assume they just typed it from memory and deactivate.

Test Plan:
  - Typed `@dog qwer zxcv` and saw autocomplete deactivate on the space before `z` (on my local install, `@dog` is ambiguous but `@dog qwer` matches nothing).
  - Typed `@epriestley ` and saw autocomplete deactivate on space.
