LLDB-DAP: Fix assert messages

Amends 0cb8760338

The assert messages look like this:
```
Debugger::Internal::DebuggerEngine(0x3170607a0, name = "LldbDapEngine")
"EngineRunRequested"
SOFT ASSERT [09:46:50.984]: "state() == EngineRunRequested" in /Users/
cristian/Projects/QtCreator/repo/src/plugins/debugger/dap/dapengine.cpp:
205
SOFT ASSERT [09:46:51.313]: "state() == EngineRunRequested" in /Users/
cristian/Projects/QtCreator/repo/src/plugins/debugger/
debuggerengine.cpp:1300
Debugger::Internal::DebuggerEngine(0x3170607a0, name = "LldbDapEngine")
"InferiorRunOk"
```
