[PATCH v2] Fix DAP Stop & Continue event bugs

[Simon Farre <simon.farre.cx@gmail.com>]

Removed type annotation as it broke gdbpy.

Fixes a bug in the stop and continue event handlers in the DAP code.

Event handlers used the `gdb.selected_thread` which may or may not be
null at the time the event handler is called. It may also return the
wrong thread. The event parameter holds the necessary data.
