run-tests: fix `HGTESTEXTRAEXTENSIONS` with py3
Since `extensions` was a str and `section` bytes, it never populated anything.
If it had, it would have put bytes into the environment dictionary that is all
str. As everything starts and ends as str, remove the incomplete attempt at
byteification. It doesn't appear that we had any test coverage of this bit of
code, so also add a non-extension config to make sure it is filtered out
properly.
Differential Revision: https://phab.mercurial-scm.org/D9557
In this test, we want to test LFS bundle application on both LFS and non-LFS
repos.
To make it more interesting, the file revisions will contain hg filelog
metadata ('\1\n'). The bundle will have 1 file revision overlapping with the
destination repo.
# rev 1 2 3
# repo: yes yes no
# bundle: no (base) yes yes (deltabase: 2 if possible)
It is interesting because rev 2 could have been stored as LFS in the repo, and
non-LFS in the bundle; or vice-versa.
