Avoid object names with '//' to avoid hash inconsistencies (#8946)

Browse Source 
This is to fix a situation where an object name incorrectly
is sent with '//' in its path heirarchy, we should reject
such object names because they may be hashed to a set where
the object might not originally belong because, this can
cause situations where once object is uploaded we cannot
delete it anymore.

Fixes #8873
