Revert "BUG/MINOR: http-htx: Don't consider an URI as normalized after a set-uri action"

This reverts commit 7533b98b8a.

This fix is reverted for now because it may introduce issues with some
config. So we want to announce the possible breakage in the 2.6.7 and
include the fix into the 2.6.8. This way, users will have some time to
modify their configuration.
