Fixed crash for pre-Qt5.6

Browse source 
Qt has garbage documentation. I dug into Qt 5.0 source code to make sure
the crashing call can be safely left out for older versions, and that is
indeed the case. setSupportedSchemes() appears to be introduced together
with the future to select non-local files in the dialog, but we only
cared about local files to begin with.
