[WebNFC] Check if NFC Settings intent can be resolved

This CL fixes a crash on some samsung android devices where the link
between ACTION_NFC_SETTINGS and the NFC settings-menu is broken. NFC
settings intent is only returned from now on only if we're confident
activity can be opened, to prevent an android java exception
"android.content.ActivityNotFoundException".
