[StGIT PATCH 5/6] Fix bash completion after the DAG appliedness patch

["Karl Hasselström" <kha@treskal.com>]

The bash tab completion used the "applied", "unapplied" and "current"
files to generate completions. Since these don't exist anymore, use
stg applied/unapplied/series to obtain the same info. It's a bit
slower, but not terribly much so.
