filename with bad encoding not listed

[m8t]

when filenames have a bad encoding, they won't be listed in owncloud.

it is possible to reproduce with the command conmv; in a utf8 environment, create the following file:

touch bléh
convmv -f utf8 -t iso8859-1 bléh --notest
ls => bl?h

put this file in a users directory under files, when listing the directory on the web ui it will output the following message in the logs:

{"app":"PHP","message":"json_encode(): Invalid UTF-8 sequence in argument at \/usr\/share\/owncloud\/lib\/private\/log\/owncloud.php#86","level":3,"time":"2014-10-22T19:42:02+00:00"}
