Remove some code in loaddata that bails out of searching for fixture files (only when verbosity > 1) as soon as attempting to open any potential fixture file fails. This code looks to have been mistakenly added in r9527; loaddata ought to proceed with attempting to locate other fixture files, regardless of verbosity setting, as it did before r9527.
