repair: setup hookargs when processing bundle2s

addchangegroup() modifies its behavior based on the transaction source.
This is incorrect for bundle2 repair files, causing rebases to abort when this
option is enabled.

This diff specifies the source type in the way recommended by comments in
bundle2.py and adds a test to ensure that rebases with the experimental option
work successfully.
