isoltest crashes on interactive update in `module_function_deployed.sol`

[blishko]

Steps to reproduce

Run isoltest on a specific test (given below), trying to update it interactively to add gas usage to expected output:

./test/tools/isoltest --no-smt -t "semanticTests/deployedCodeExclusion/module_function_deployed*" --enforce-gas-cost --enforce-gas-cost-min-value 0

First, isoltest asks if we want to update expectations. On update, the test is re-run with updated expectations and isoltest crashes:
