ExceptionHookImpl: Identify exceptions cause by MissingObjectException

Missing Git objects are often the cause of exceptions and we would like
to track in our metrics how often they occur. By returning a unique
string as cause, occurrences of this exception go into a separate metric
bucket.

This also reduces noise in the metrics which allows us to see how many
remaining unknown causes of internal server errors there are.
