bundle: do no check the changegroup version if no changegroup is included
We don't need to check the compatibility of something we will not use.
In practice this was getting in the was of `streamv2` bundles on a narrow
repository as the 'cg.version=02' value was rejected by this checks.

There are some web servers in the wild that can serve static files with an
incorrect encoding (e.g. https://bz.mercurial-scm.org/show_bug.cgi?id=6559).
One way to prevent any issues is to not use any non-ASCII characters, e.g.
URL-encoding them or using HTML entities.
check charset of all tracked files ending in .js
