commands.remove: don't use workingctx.remove(list, unlink=True)

workingctx.remove(list, unlink=True) is unsuited here, because it does too
much: it also unlinks added files. But the command 'hg remove' is specified
to *never* unlink added files.

Instead, we now unlink the files at the commands.remove level (if --after was
not specified) and use workingctx.forget for all files.

As an added bonus, this happens to eliminate a wlock acquire/release pair,
since the previous implementation caused

   acquire wlock
   release wlock
   acquire wlock
   release wlock

where the first pair of acquire/release was caused by the workingctx.forget
call, and the second by the workingctx.remove call.
