[lldb-dap] Assorted small fixes for runInTerminal

- CreateRunInTerminalReverseRequest is passed a StringMap by value, whose keys
  are owned and deallocated after return.
- Target args are wrongly specified as reverse request (launcher) args.
- Test case error message did not catch up with a0aa5f8.

All runInTerminal tests are passing with this applied.
