rebase: stop clearing on-disk mergestate when running in memory
In-memory merge no longer uses on-disk mergestate since
19590b126764
(merge: use in-memory mergestate when using in-memory context,
2020-09-15). This patch removes the clearing from two places in the
in-memory rebase code. I've verified that the one with a TODO was
indeed fixed by the aforementioned commit. The other instance doesn't
seem to have any test coverage, but I'm pretty confident it's also
safe to remove.

Error: the current ro localization has some rst defects exposed by
moving pager to core. These two warnings about references are expected
until the localization is corrected.
