Sentry uses incorrect stacktrace for CoreCrashedError

[drew2a]

An example: https://sentry.tribler.org/organizations/tribler/issues/2480

Stacktrace:

PyInstaller\loader\pyimod03_importers.py:495
UserWarning: You are using cryptography on a 32-bit Python on a 64-bit Windows Operating System. Cryptography will be significantly faster if you switch to using a 64-bit Python.

CoreCrashedError
The Tribler core has unexpectedly finished with exit code 1 and status: 0.

Error message: Application error

Should be:

CoreCrashedError
The Tribler core has unexpectedly finished with exit code 1 and status: 0.

Error message: Application error

This results in CoreCrashedError mimicking unrelated errors, making it invisible in Sentry:
