Code review comment for lp:~michael-sheldon/webbrowser-app/file-upload

When clicking on the cancel button of the picker, I get this error:

file:///home/osomon/dev/phablet/browser/webbrowser-app/src/app/ContentPickerDialog.qml:54: TypeError: Property 'dismiss' of object oxide::qquick::FilePickerContext(0x32d1b30) is not a function

you will need to s/dismiss()/reject()/ in src/app/ContentPickerDialog.qml.
