getSize with garbage in the directory structure
-----------------------------------------------
`getSize` iterates over the existing blob files in the blob directory and adds
up their size. The blob directory sometimes contains temporary files that the
getSize function needs to ignore:
>>> garbage_file = os.path.join(blob_dir, 'garbage')
>>> open(garbage_file, 'w').write('garbage')
>>> int(blob_storage.getSize())
881
Note: This is a counter measer against regression of bug #12991.
