TerminalTest fix potential leak of memory

The "return" in "#define QCOMPARE(actual, expected)" does not allow us
to delete the new-ed objects. This raises clangd "konsole/src/autotests/TerminalTest.cpp:28:5:
Potential leak of memory pointed to by 'display' [clang-analyzer-cplusplus.NewDeleteLeaks]"
and PVS-Studio V773.
