urlutil: move url "fixing" at the time of `ui.paths` initialization

Doing such fixing at the time is simpler and will be necessary to deal with
urls list in a sane manner. It also reduce the size of fix-config which is
always better.

I wish we could get ride of the hackish way to pass the root around, I suspect
that the `root` variable could be stored as part of the config value, along side
the source. However getting to the end of this `root` business is a far too
large detours to make now.

The test change to `tests/test-hgrc.t` and `test-config.t` are expectied since
we are not longer altering the config itself, but the way it is interpreted when
building path.  This seems more correct.

I also added a couple of test call to `test-config.t` and `test-globalopts.t` to
clarify that the expanding process is properly happening a the right time.
