test_call_insufficient_balance()

Documentation for tests/berlin/eip2929_gas_cost_increases/test_call.py::test_call_insufficient_balance@e9958ed2.

Generate fixtures for these test cases for Osaka with:

fill -v tests/berlin/eip2929_gas_cost_increases/test_call.py::test_call_insufficient_balance --fork Osaka

Test a regular CALL to see if it warms the destination with insufficient balance.
