largefiles: move "copyalltostore" invocation into "markcommitted"

Before this patch, while "hg convert", largefiles avoids copying
largefiles in the working directory into the store area by combination
of setting "repo._isconverting" in "mercurialsink{before|after}" and
checking it in "copytostoreabsolute".

This avoiding is needed while "hg convert", because converting doesn't
update largefiles in the working directory.

But this implementation is not efficient, because:

  - invocation in "markcommitted" can easily ensure updating
    largefiles in the working directory

    "markcommitted" is invoked only when new revision is committed via
    "commit" of "localrepository" (= with files in the working
    directory). On the other hand, "commitctx" may be invoked directly
    for in-memory committing.

  - committing without updating the working directory (e.g. "import
    --bypass") also needs this kind of avoiding

For efficiency of this kind of avoiding, this patch does:

  - move "copyalltostore" invocation into "markcommitted"
  - remove meaningless procedures below:
    - hooking "mercurialsink{before|after}" to (un)set "repo._isconverting"
    - checking "repo._isconverting" in "copytostoreabsolute"

This patch invokes "copyalltostore" also in "_commitcontext", because
"_commitcontext" expects that largefiles in the working directory are
copied into store area after "commitctx". In this case, the working
directory is used as a kind of temporary area to write largefiles out,
even though converted revisions are committed via "commitctx" (without
updating normal files).
