Autotext correction would check whether the first suggestion
so far was the same as what Autotext would return, and if it
was indeed the same, would not send its result as
autocorrect. However, the first suggestion is not guaranteed
to have a high enough score to trigger autocorrection, and
there would be cases where a word in autotext would not get
autocorrected because the word came out of bigram
suggestions. These occurrences would be extremely rare, as
they would require concomitant insert between autotext for
one char and bigram suggestion. It is, in fact, probably
limited to the capitalization of "I".

This did not happen in gingerbread because gingerbread would
not register 1-letter words as valid bigrams.

This fix works by just always sending the result of autotext
regardless of whether it is already the first suggestion or
not. This is okay because duplicates are removed afterwards
anyway - and this processing is absolutely necessary because
the autotext'd word may actually be somewhere else in the
suggestion, so it made really no sense checking for only the
first one.

Please note that there is also a race condition that can
result in "i" not being converted to "I": at the moment,
Latin IME relies on having the suggestions evaluated
at the time autocorrection is performed, but when typing
very, very fast, those messages may have been canceled.
This is not limited to the autocorrection of "i", but
affects all autocorrections. It requires a nearly
inhumane typing speed to trigger, but hitting "i" and
space in turn as fast as one can it's possible to
reproduce occasionally.
