[BUGFIX] Catch Exception while extracting metadata

Catch InsufficientFileAccessPermissionsException while extracting
metadata. Reason for this exception could be that the file extension is
not allowed by the ['BE']['fileDenyPattern'] setting.

This patch makes sure that the indexer doesn't break and is able to
extract the other files from storage.

Resolves: #82060
Release: master, 8.7, 7.6
