Bu::MyriadCache was truncating existing dbs.HEADmain

When opening an existing database, while loading the index
Bu::MyriadCache would open it with the WriteNew option, even though it
didn't need to write. This now truncates the stream appropriately, so it
never found any data and proceeded as though it was a new database.
