fix: no command completions if query/line is an alias

basically, i have a `c` alias which is `git commit`,
this would resolve to `git commit` literally to try
and complete `commit`, which wouldnt match.
this fixes that, and instead itll suggest commands
that start with `c`. if there is a space after and
completion is requested, itll use the alias properly
