IC tests: make exceptions from compiler more visible in tests

otherwise they are easily swallowed by the reporting logic.
This commit was needed to ensure that the problem described in
KT-63665 is reproducible in IC test
But some JS IC logic relies on handling compiler exceptions as a signal
for scope expansions, and the newly introduced exception logging
broke a few tests. To mitigate it, the directive was introduced
to disable exception logging for particular test.
