util: fix indentationLvl when exceeding max call stack size
The inspection indentation level was not always reset to it's former value in case the maximum call stack size was exceeded.
It did not seem to be critical to add a test case for this as it's a pretty special case that has no completely reliable output anyway (the stack limit is not going to be identical on each run). Please let me know if you feel I should add a test nevertheless.
