commands: execute checkunfinished and bailifchanged inside wlock scope

Before this patch, "hg import" executes below before acquisition of
wlock:

  - cmdutil.checkunfinished()
  - cmdutil.bailifchanged()

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

To avoid this issue, this patch executes 'cmdutil.checkunfinished()'
and 'cmdutil.bailifchanged()' inside wlock scope of "hg import".
