revlog: make sure we never use sparserevlog without general delta (
issue6056)
We are getting user report where the delta code tries to use `sparse-revlog`
logic on repository where `generaldelta` is disabled. This can't work so we
ensure the two booleans have a consistent value.
Creating this kind of repository is not expected to be possible the current bug
report point at a clonebundle related bug that is still to be properly isolated
(Yuya Nishihara seems to a have done it).
Corrupting a repository to reproduce the issue is possible. A test using this
method is included in this fix.
