[PATCH] fetch2: Fix AUTOINC handling

[Richard Purdie <richard.purdie@linuxfoundation.org>]

AUTOINC was meant to appear once at the start of the version string.
The list of names may not be sorted meaning it could get inserted in
the middle. This patch simplifies the code and ensures it appears at
the start.

Include cache version bump to ensure the cache picks up these changes.
