shelve: widen wlock scope of unshelve for consistency while processing

Before this patch, "hg unshelve" of shelve extension executes below
before acquisition of wlock:

  - cmdutil.checkunfinished()
  - examine existence of (specified) shelve file

It may cause unintentional result, if another command runs parallelly
(see also issue4368).

This patch widens wlock scope of "hg unshelve" of shelve extension for
consistency while processing.
