[PATCH 3/3] tests: try next tshark filter for UnknownFieldsException

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

The intention in commit cc35ed3e257a ("tests: Permit passing multiple
valid tshark filters") was to permit passing multiple filters in order
to permit compatibility with older tshark versions. However, this did
not work as expected for the UnknownFieldsException.

Fix that by storing it in last_exception as for other errors. This fixes
running some EHT tests with older tshark versions.
