Tests that the "scopes" request causes the currently selected
thread and frame to be updated. There are no DAP packets that tell
lldb-vscode which thread and frame are selected other than the
"scopes" request. lldb-vscode will now select the thread and frame
for the latest "scopes" request that it receives.
The LLDB command interpreter needs to have the right thread and
frame selected so that commands executed in the debug console act
on the right scope. This applies both to the expressions that are
evaluated and the lldb commands that start with the backtick
character.
