fix(evm-wallet-experiment): distinguish prettified errors from manifest constants

prettifySmallcaps converts both #error objects and manifest constants
to strings starting with "[": errors become "[TypeError: msg]" while
constants become "[undefined]", "[NaN]", etc. Use a regex that checks
for the ": " separator to avoid false positives on void method returns.
