[Bug] attack wolframalpha.py doesn't work at test

When running $ RsaCtfTool --test to verify test cases, I encountered an issue where the 19th attack fails silently without producing any output logs. While all other 59 attacks correctly display failure logs when they fail, this specific one does not output anything at all.

After reviewing the attack files in src/RsaCtfTool/attacks/single_key/, I have identified that wolframalpha.py is the one causing this issue.
