This is an incompatible change: Before this change, if a file is already open for write by one client, and another client calls fs.create() with overwrite=true, an AlreadyBeingCreatedException is thrown. After this change, the file will be deleted and the new file will be created successfully.

Description

If a file is already open for write by one client, and another client calls fs.create() with overwrite=true, the file should be deleted and the new file successfully created. Instead, it is currently throwing AlreadyBeingCreatedException.

This is a regression since branch-1.
