rebase: fix regression in file change detection introduced by 0ecb3b11fcad

Before 0ecb3b11fcad, `wctx._compact()`, was called by `wctx.nofilechanges()` as
a side effect. Later, it turned out that this side effect is needed to correctly
detect which files changed. See https://phab.mercurial-scm.org/D8733#131949 for
the history.

The problem could also be triggered by running `tests/test-rebase-parameters.t`
with `--extra-config-opt rebase.experimental.inmemory=1`.
