Add option to mark user-rejected calls as missed

This patch adds an opportunity to mark user-rejected calls
as "missed" rather than "incoming" in call log. Option is
useful for regions where voicemail is not quite widespread
and for users who need reminders about previously rejected
calls.

PS2: fixed a derpz0r
