test: drop the assertion for the removed ambiguous-means-task example (#3030)

#3028 removed the 'treat ambiguous requests as tasks' rule and its
'locate the method in the code' example from the default system prompt.
The profile test pinned that example verbatim, so it now fails on main.
The removal was intentional; update the test to the new contract.
