AutoCorrect: fix not immediately replacement of Emoji :short_names:

Cherry-picked from 86782d5d
and cd2ba312.

[86782d5d:

AutoCorrect: direct replacement of keywords surrounded by colons

Replacing immediately (without pressing space or enter) and
inside words, too. For example, fixing tdf#55292 – complete input
method for n-dash, m-dash – is possible now by  :--: -> n-dash,
:---: -> m-dash AutoCorrect replacements.]
