Handle cancel in PreferencesDialog::on_chooseFile_clicked

Browse Source 
If I click in the Preferences Dialog on the 3 dots to choose a default
file to load and cancel the opening FileDialog an empty string is returned
and set to the coresponding QLineEdit.

The new behavior (and mostly expected) is to update the QLineEdit only
if there is a filename returned from QFileDialog.
