Fixes bug 1089140. Turns out that if an exception bails out of the pickle loading (eg. zero-byte hahes_file), the if clause to determine whether or not to write out a fresh hashes_file can evaluate to false, leading to an infinite loop. This patch fixes this infinite loop generally, by ensuring that if any exception is thrown, a new hashes_file is written. Change-Id: I344c5f8e261ce7c667bdafe1687263a4150b21dc
