ErrorProne: Enable and fix UnusedException check
Enable UnusedException at ERROR level which causes the build to fail
in many places with:
[UnusedException] This catch block catches an symbol and re-throws
another, but swallows the caught symbol rather than setting it as a
cause. This can make debugging harder.
Fix it by setting the caught exception as cause on the subsequently
thrown exception.
Note: The grammatically incorrect error message is copy-pasted as-is
from the version of ErrorProne currently used in Bazel; it has been
fixed by [1] in the latest version.
