Make me work with owncloud9

Due to API change (searchByMime), app was completely broken when
installed with owncloud9. This change should make it work with
owncloud9, while still keeping older owncloud version (upto 8.2)
in working state.

Lets use functions on object returned by searchByMime instead of
directly accessing its data members.
