[PATCH] [WineDbg]: bt all

[Eric Pouech]

- fixed regression for command 'bt all'
- don't print 'process has terminated' message when
  detaching from a process (or backtracing it)

In details:
- bt all would crash when several processes were run
- bt <tid> could return a wrong back trace under some
  circonstances
