tests: use `hg unbundle` instead of `hg pull` in some tests

`hg pull <bundle>` uses the special "bundlerepo" repository. The
bundlerepo code makes many assumptions about the storage of
repositories. It will be difficult to teach bundlerepo to use
non-revlog storage before a better storage interface is established.

Many test failures using our "simple store" are related to
bundlerepo: the simple store just isn't compatible with bundlerepo
because of storage assumptions in bundlerepo.

In order to mitigate the impact of bundlerepo on our code base,
this commit changes various tests to use `hg unbundle` instead
of `hg pull`. This bypasses the bundlerepo code.

Tests exercising exchange functionality have not been altered, as
they should be using `hg pull` and going through the bundlerepo
code paths.
