overlayworkingctx: rename misleadingly named `isempty()` method

This method is only about whether there are file changes, not about whether the
commit will be empty or not.

One user of the method was incorrectly assuming the latter meaning, leading to
the bug for which a test case was added in D8727. I’ve added a FIXME to the
code.

The original motivation for the rename was that I want to add
`committablectx.isempty()`, that properly checks if a commit will be empty,
using the exact same logic as in `repo.commit()`, and I wanted to avoid a name
clash.

Differential Revision: https://phab.mercurial-scm.org/D8728

== New Features ==

 * The amend extension supports the `--currentuser` argument.

 * The amend extension supports the `--close-branch` argument.

 * The amend extension supports the `--secret` argument.

 * The uncommit extension supports the `rewrite.update-timestamp` config option.

== New Experimental Features ==


== Bug Fixes  ==


== Backwards Compatibility Changes ==

 * A shell that supports `$(command)`` syntax for command substitution is now
   required for running the test suite. The test runner normally uses
   `sh`, so if that is a shell that doesn't support `$(command)` syntax,
   you can override it by setting `$HGTEST_SHELL` or by passing it to
   `run-tests.py --shell <shell>`.

 * The (experimental) narrow extension's wire protocol changed. If
   you're using it, you'll need to make sure to upgrade server and
   client at the same time.

== Internal API Changes ==
