`piexif.dump` errors are not safely handled

Sentry link

https://sentry.io/share/issue/a80d52de7f89436586ed0250cd0a32d2/

Description

The call to piexif.dump should be wrapped in a try/except to prevent these errors in the watermark endpoint.

Reproduction

Visit https://api-dev.openverse.engineering/v1/images/a913fde1-d524-4059-bd4f-9bd687578cc3/watermark/ to see an example of this failure.

Closing this in favor of #827, as both Sentry errors are manifestations of the same issue. I'll also merge the Sentry issues together.

We're not catching all the exceptions on this code block so reopening.
