dirstate: wrap repository change in appropriate context in `test-context`
We need the `wlock` (to add files), the `lock` (to commit), a `transaction` (to
commit) and a `changing_files` context (to add files).
Strictly speaking, we could let the commit take the `lock` and create a
`transaction`, but it seems more consistent that way.

providing a .hg/pullbundles.manifest according to the syntax specified in
'hg help -e clonebundles' is enough.
